Microsoft games never seems to change their game engine. graphics. gameplay. how the characters looks like. weapons and almost everything in the game by much. just a slightly different story! even HALO and anything they make!
i noticed that too they only have 2 exclusives halo 4 and gears and they both feel like a rehash just slapped on a new name thats why i got a ps3 they work hard on thier exclusives for example the last of us, uncharted and many other titles microsoft is just trying to make more money
