OVERVIEW
 
Mega Man Wily Wars also known as Rockman Mega World in Japan is a re-release of the first three Mega Man/Rockman games for the Sega Genesis complete with a few changes here and there to take advantage of the superior 16-bit technology of the Sega Genesis/Megadrive. Once you have completed all three games in any order you choose, then you get a bonus game called Wily Tower where you take on three extra bosses and a brand new set of levels. I am covering the Rockman Mega World version of this game as the PAL version is utter puke due to the lower frame rate and god awful soundtrack.

DIFFICULTY/GAMEPLAY - A-
 
I decided to add difficulty to the Gameplay area for this game because it is important and I knocked down the grade a little bit because of it. Now I bet some of ya'll are wondering why I gave the difficulty a 7. As much as I hate to do so, it is totally justifiable if you are playing this game after you have played the first three games on the NES. First off let's begin with the hit detection. There are a lot of things that you are going to get hit with that you would not have done so in the NES and on the same token, there are some shots you would normally connect with, that will often miss in this game too. Let's take the Quick Man boss fight from Mega Man 2 for example. In the NES version, you could be a step higher than him and still hit him with your normal shots but in Wily Wars, the shots will sail over his head and thus make this fight even tougher if you decided to take on him first. Going against Heat Man's stage also in Mega Man 2 without getting Item-2 (obtained from Airman) is also a bad idea as the Yoku blocks appear out of sync and make this level unplayable near the end of the level when you got to use the Yoku blocks to get past the lava pit and the deep pit that follows.Fortunately, the boss fight is a bit easier to deal with this time around as you can always start the fight by running towards Heat Man and his opening shots will always sell over you for a free hit as opposed to the NES version's difficulty in avoiding the first volley of shots. Remember that is still easier to get hit by his flaming charge even though you jumped over it. The sentiment also applies to the Hari Hari (porcupine) enemies you often see in Needle Man's stage (in Mega Man 3) when they roll.
 
Another aspect that has been made both easier and harder, depending on where you are in the game, is the threshold of floor contact you have when you land. There are cases where in the NES, you would fail to stick the landing on a platform and fall down the side of it. Here, you can be a few pixels off of where you are trying to land and still stick the landing. Although this sounds easier on paper, it can also harm you as well as you may end up failing to fall down when you want to walk off a ledge and go into the other direction as you fall. That is a killer in Quick Man's stage if you are brazen enough to take on his stage first instead of acquiring the Time Stopper from Flash Man first. The damage values have gone up a little bit in some games as in Mega Man 2 final boss. The alien boss has insane contact damage that takes away 75% of your energy. However, not all changes were made to be harder. Some of the easier changes was to Ice Man's stage in Mega Man 1 where underwater physics were given to the water areas that were not present in the NES version. The Top Spin from Top Man's stage is safer to use now against bosses as well as enemies who are immune to it. The way Top Spin worked was if the enemy did not die in one hit, the enemy was immune to it and you would take damage. However, if you fought a boss who was vulnerable to it, you would always end up trading hits if they still had energy left. On top of that, the use of Top Spin would drain rapidly against immune and vulnerable non 1-hit kill enemies. Now when you use it, it will pass through the enemy sometimes with no damage done to you and you could also harm bosses without trading hits if careful. The Rock Monster from Mega Man 1 has somewhat lower difficulty because the bits move slow but the pattern has changed a bit so call it a neutral change.
 
GRAPHICS - S
 
The graphics got a wonderful upgrade. Mega Man, the bosses, all the stage enemies are modernized for its time but the main winning selling point of the graphics category is all of the stages got a major overhaul. A lot of them are excellent but some I am not to fond of like Gemini Man's stage from Mega Man 3 which adds an unnecessary jade to the changing crystal colors, they should have been left alone. The stage I do like the most is Fireman's stage from Mega Man 1 where the background sways back and forth as one would expect if you are inside sweltering heat. The user interface was added in Wily Wars to give a good graphical look at the weapons you currently have in your possession. My only gripe here is the Magnet Beam. It used to come out as one quick firing platform beam to help you get across faster but now it comes out much slower as its all broken up into bits.
 
CONTROLS - A-
 
As much as I hate to take off points for this, there is more to controls than just moving around and jumping and shooting. There is also a matter of response too. Let's talk about shooting. In the NES, you could gun down most enemies before they had a chance to react. 
 
Note: This does not apply to Mega Man 1 NES as all enemies had after hit invincibility without the pause trick.
 
In this game, you can barely get off shots quick enough to defeat some enemies fairly quick like the aforementioned Hari Hari as well as the Hammer Joes. In fact, your shot are slow enough were if you are given a burst of speed, you can keep up with the bullet on the screen. The other aspects are still intact as you have the choice to choose what controls what in this game. A is used for window, B is shot and C is jump. Since I use the PS4 controller to play it on the emulator, I assign Shot to A, Jump to B, and Window to C since its a staple for modern games these days to put shooting button on the left and jumping on the lower center button. 

SOUND/MUSIC - A (JP)/C- (PAL)

I love the remixed versions of the Japanese version's music and it is very catchy. The PAL version's music is enough to drive me insane because it sounds totally off key. I know it's because of lower framerate but it still comes up short with me. The Wily Tower music is even catchier. One of the tracks reminds me of a song by the music group, DeBarge.
 
REPLAYABILITY - S
 
Three games in one plus an added bonus game is definitely worth playing over and over again because when you get to the Wily Tower, you get to use a lot of experimentation throughout the levels to see what to use and what not to use each time you play as you are given the choice to choose which 8 weapons and 3 assists you want to use.
 
OVERALL - A+ (JP)/C+ (PAL)
 
It is a shame that this never got a cartridge release in the States and ended up being relegated to being playable exclusively on the long defunct Sega Channel along with Alien Soldier and Pulseman. Those would have been totally awesome to play in the West. It is possible to import but the PAL version is too slow for my tastes.

Great review, but I am pretty sure that using numbers woould be better than letters. Also it did come to the west if I'm not mistaken.

It didn't get released in physical format. It was only a Sega Channel release out here.

I don't think this one was quite as amazing as you're describing it to be. It's basically the NES games with slightly nicer graphics and sound. Aside from the Wily Tower, there's really no reason to play this game if you've played the first three games on the NES. There's also the issues that you've noted in this review, like the unwelcome changes that make the game feel less balanced than the NES version. There's also the fact that the version of Mega Man 2 on this cartridge doesn't have the difficulty selection, so the version on a technologically superior console is actually missing features that were on the 8-bit console version. With all that stuff out of the way, though, your review is well-written, aside from the occasional spelling and grammar error.
