Grand theft auto four is one of my favorite games ever. It had a great story line, graphics were good for its time, the sound was really good, and it had great voice acting. Grand theft auto 4 was extremely addicting, it took me months to beat the story, and I spent allot of time free roaming around the open world. The story was long, and engaging. It was great. You always felt like you were attached to the characters, and you always felt for the main character, because of the things he goes through. The depth of the game is really good, to. You have allot to do, and you always were occupied. Whether you were killing hoards of police, or you were going bowling, or playing pool, you always had something to do. The graphics were good, if you consider when it was released. The sound was decent, for its time. The game wasn't that hard, but it got me at some points. One of the most outstanding things is the euphoria game engine. You would never get bored of launching Niko off of his bike and watching him fly through the air with realistic physics. Also, if someone is near a railing, and you shoot them, they will fall off of it realistically. With rag doll physics, they wouldn't go over, they would just slump down.
   If you haven't already, get this game. You won't be disappointed.

This was actually good for your first review. I think you need to put them in to categories though like this.
 
 Graphics:
 blah blah blah or whatever you wanna put here.
 
 Other than that this was actually a really good first review.
 
 Keep on writing!

Never played 4, but I have played 3, which I have heard is better then 4.
Not bad review.
I would recommend breaking it down more and adding some detail.
But not bad.

Although I have never played these games because they don't really look appealing to me, I think you did a decent job reviewing this game considering this is your first review. I recommend that you split your review up into categories and then go from there with talking about each one in detail. Once you do that it should be easier to accumulate words to make a lengthier review. For the most part, that is pretty much all I can suggest for this review because once you break it down, then it becomes more organized and then you can discuss all of the main points from there. 

For length, just keep reviewing because the more you review, length should come naturally and it will become easier for you to make longer reviews. Keep at it and I assure you that you will become a better reviewer! 

Barathemos: GTA 3 is in no way better than GTA 4. It was revolutionary in its time, but GTA 3 has not aged well in time. GTA 4, though, is still perfectly playable, even with GTA 5's better vehicle handling. And I'm pretty sure that GTA 4 will age better than GTA 3, too. ^^'
