My review is what you are looking for.
Finally, at 3 pm today, I got SR2. I was so eager to play this game when I got home. So I hurried to my xbox 360 and inserted the game. Soon as I turned it on, I saw the cool volition thingy which made me a little bit more jumpy.
Making my own character excited my brain. I tried out many different types of hair, taunt, and more. Controls were very easy to get use to. I only spend, like 5 min just trying to figure out what the controls were. Graphics were great. Some of people said this game's graphics were horrible........well they're maybe blindfolding themselves or they're blind. The city looks beautiful! Trust me, all those youtube + other videos you saw are not the same as when you look at it in your t.v.
SR2 has many new features. Throwing, bodysheilding, new fighting systems and much more. My favorite new feature was the respect system. Everything that I did mattered!! In SR1 respect bar didn't go up when you did a powerslide or a big jump. But now if you do something cool, you get a little bit of respect points. Another new features were new vehicles. Motorcyles, boats, airplanes, and that huge Ultor vehicle. Volition really did their job this time. There are so many new features, but I don't write them all down.
SR2 is better than GTA4. I know it for sure. I used to love GTA4 but now I'm on SR2's side. Trust meeeeeeeee!! If you are still confused about getting SR2 or GTA4, get SR2. I was just like you!!!! So get your big ass off of that chair and go to bestbuy then buy SR2.
