@ERoBB: Interesting read, though there are a few I would add.
Really? GTA would probably be one my examples of how to do it right. They only release a game every few years, and it's always a significant leap forward.
Ya but it is always the same game you drive you shoot stuff you brake the game been there done that.
but driving and shooting and breaking stuff is so damn fun! I never get tired of the GTA games, although GTA IV lost a little bit of the fun factor of San Andreas and Vice City.
