I watch a lot of YouTube videos. I would likely watch more if I didn't have to go and learn at college. Who needs smart? Anyway, these are the guys that I think are awesome. In alphabetical order nonetheless.

Balrog the Master
He does videos centered around Nintendo. From Reviews to him voicing his opinions. I like his videos a lot, and if you are a die hard Nintendo fan then you will like his channel. (Though I don't think it matters if you like Die Hard)

BlueXephos
The Yogscast. The best when it comes to Minecraft videos. They do videos about new games as well. They do a fair few Garrys Mod videos. You likely already have them on your subscribe list, but if you don't I definately reccomend checking them out.

Brentalfloss
It's strange how popular someone can become from doing something so simple. Brent Black adds lyrics to the most well known songs in gaming, and with his large knowledge of music makes impressive songs to listen to. His attitude is likely what makes us keep coming back to him.

Caddicarus
This guy is pretty much the slightly older version of me. He plays PlayStation games and loves it. It may just be because he is british that I like him, but I feel he is really good at what he does. If you like guys such as Angry Video Game Nerd and JonTron, then you will really like Caddy.

Corridor Digital
These guys are a group that make really impressive videos, with incredibly well done effects. The main focus of most of their videos are the effects. They have done a few videos which are based around games which are especially impressive. A definate must for those who love eye candy.

Cruelest Chris
Evil Tim on other sites, and as he introduces himself in his videos. He is a let's player who has a very large knowledge of the games he plays and many, many wisecracks to each one. His main console that he chooses games for is Nintendo 64, which he records using a capture card, not using an emulator. He does do let's plays for games on other consoles too, but his best are on N64. The only downside is he does not finish all of his lets plays, and recently has been rather slow with videos.

Cyriak
Makes the weirdest videos you will ever see on YouTube. His videos are all based around image manipulation, which is something he is incredibly good at. His videos are the ones where my friends go "This is the kind of stuff to watch while you're high!" Incidentally, if you are high, stop reading now.

Did You Know Gaming?
I thought I did until I watched their videos. They get popular guys from the internet to do videos outlining all of the interesting facts about a game, or game series. Sometimes these span several videos. They also have their own website which is absolutely full of facts about games. They partnered with the Spriters Resource to make a second website known as VG Facts.

Egoraptor
Makes flash animations based off games. These are known as the Awesome Series. They usually rip apart the story, or a key feature of a game. The only real downside is that their quality fluxuates rapidly, so there is no knowing if one of his videos is actually going to be good. They usually are though.

Element Animation
Makes 3D animations. Usually about eggs. These eggs talk, and their adventures have a tendancy to span the internet. As in encountering memes for example. Some popular internet guys are sometimes on it as well. The quality of the animations is very good, and there is never any drop in this.

Frob Man
AKA Till man. Makes animations similar to Egoraptor. His animations are also fairly random in quality, but they are not strictly about games. He will make an animation about any subject he wants it seems at times. His animations about games are based around the entire story of the game, usually commenting on the level design. He has in incredibly british sense of humor. If you like Monty Python you should like Frob Man.

Gaijin Goomba
Makes videos that explain the connections between gaming, and Japan. These are called Game Exchange. He has done some that are not about linking games with Japan, but that seems to be his main focus. And I would not change that. He does a great job at it, and everything he says is completely true and very interesting.

Game Grumps
The combined powers of Egoraptor and JonTron create... Game Grumps. This is a channel where both of these crazy lunatics play games together, whilst talking about random crap. Usually they are taking the piss out of the game they are playing, but do have a habit of going on tangents. If you like watching Let's Play videos, these guys are for you.

Harry Partridge
Makes cartoons. Makes very good, high quality cartoons. Harry has a very old style sense of humor when it comes to what he makes. His cartoons are very reminicsent of the things that came out it the 70s-90s. It is my style of humor. He makes sure that his videos are well made and his quality is improving with his videos, slowly but surely.

Ian Hecox
The other channel that has Smosh videos on. These usually consist of Ian is Bored and Lunchtime. Most of this is filmed on the spot, and is not rehearsed. This pretty much just Ian and Anthony just being themselves.

IGN
The second place I go for game information (Right after TotalBiscuit) as anything that comes up in the world of gaming, large or small, will have a video on this channel. Pretty much every game gets a review and full coverage on this, so if you are looking into new games, this is the perfect place to look.

James Rolfe
As most of you know him, the Angry Video Game Nerd. He reviews old games, usually on the NES. He targets bad games. His reviews will usually come with some kind of act, such as a fight with the character. He has a friend, Mike Matei who makes videos on good games, and also draws the titles for each of James' videos.

JonTron
Makes game reviews of old games, new games, and games that are kind of new, but could be considered old. He makes very over-the-top reviews of games that are very memorable to different people. Of course the reasons for these games being memorable vary. He is a very funny man, but I must warn you, if you don't like shouting, avoid.

Jump in the Pack
A League of Legends based channel. There are chamption and skin previews, fail plays, and penta kill videos, to name a few. He will personally comment through all of his videos, and always knows his facts about what is going on. I reccomend this one to League of Legends fans of course.

Lazuli Films
Makes videos about PC games. Their videos are usually Minecraft based, but they play some other games as well. Similar to Yogscast, but on a smaller scale. One of the main guys in it, Sparky is a good friend of mine from College.

LittleBigPlanetorials
As you can likely guess from the title, makes tutorials for LittleBigPlanet. While most at home on LittleBigPlanet 2, videos are made for LBP Vita. The tutorials cover the most useful aspects on creating, and are incredibly useful. I highly reccomend this to anyone who plays LittleBigPlanet 2, or LittleBigPlanet Vita, as the tutorials for LBP2 will apply to Vita.

Machinima
Makes every kind of gaming video possible. You name it, they have done it. A huge channel with a colossal community. Just, watch yourself. You could lose your soul watching these. I reccomend that everybody at least trys this channel.

Mathew Patrick Game Theory
Makes videos explaining the logic behind a feature of a game. His videos are very scientific, and to understand require some scientific knowledge. He knows the games well enough to back up any arguments he makes. A good channel for those who like to question games.

OneyNG
Makes cartoons, similar in style to Egoraptor, but without a real main target. His videos will be about anything, but are incredibly well made. Worth a look at least.

Peanut Butter Gamer
Another one of those lunatic game reviewers. This one has a large emphasis on the Zelda games. He will do videos that arent reviews. I can't really say more without repeating what I said about other guys.

RabbidLuigi
I felt I need a guy for top ten lists. This guy is pretty good at it. Has several about Zelda.

Rage Ninteen
Another guy who mankes cartoons. Most based around games. They are however usually short. He makes videos on many different subjects.

Retsupurae
When someone says Let's Play video, the first channel that comes into mind is this one. They usually make videos of them voicing over someone elses Let's Play. They only do this to bad ones. You could use those videos as a guide as how not to make a Let's Play video.

Robbaz
Makes videos about screwing around in games. He is rather random about this. I just have to warn you, he is incredibly immature. And swedish.

SexualLobster
Makes very immature cartoons. If you have a crude sense of humor, you will love them. Makes cartoons based on certain community creations. Very high quality stuff as well.

Smosh
Quite possibly the most famous guys on the internet. Smosh make videos based on movies, games, jokes. They make up fake adverts for terrible products, and generally make purely random videos. They have been going since YouTube began. Definately worth watching. Also check out their other channel, this one is solely dedicated to games, and features different sections for this.Smosh Games

TotalBiscuit
Makes videos of the different new games that come out on Steam. He also makes in depth analasys of gaming news. I would say the greatest guy when it comes for information about games. He puts up videos all the time, and stays up to date.

Vsause, Vsause2 and Vsause3
In depth analasys about science, games, whatever comes up. The three different channels feature different subjects, each with a main theme. If I was to list everything that they did then I would be here forever. I reccomend these to everyone who uses YouTube. They have stuff that will appeal to whoever goes on their channels.

That was quite a list.

Go on youtube and watch some videos by "HowToBasic". I dare you all!

If you're a Pokémon fan, some good channels to check out would be that of JWittz and TamashiiHiroka. If its gaming in general that you want, some good ones are SomeOrdinaryGamers and AngryJoeShow. 

Thepastaking does pretty decent lets play sessions. He recently returned, but I do not know his schedule. If he starts posting more lets play he is worth a check.

Pewdiepie and Machinima are easily the best I also watched several reviews of Peanut Butter Gamer and those didn't nake me fall asleep and some gameplays that he had done in the past.

Chugaaconroy is easily the best Nintendo lp'er I think that he is way better than the Rabidluigi since I didn't know he still done videos.

Didyouknowgaming is a very interesting channel I actually enjoyed them alot they went behind the scenes in creepypastas and several other unique rumors.

Gamegrumps several videos they made had made me laugh I couldn't even breath.

And thats about it.

Never heard of JonTron  Might just see what its about.

My favorite youtube channel is Super Mario glitchy 4 or Mario Mario 54321.
