Gremmi: Key point - "Innovation" != "Doing something for the first time".
wodmarach: No but it does mean being original... even the developer of Heavy rain calls it an evolution of indigo prophecy but as I said you don't really get it in AAA titles you can't afford to spend 20million+ on a game that might only sell to 20 people so you do a small game to test the innovation a B movie of a game if you will
It's possible to innovate without being risky. Look at Medal of Honor Airborne. Alright, it wasn't a fantastic game, but it took several staples of the FPS genre and innovated with them (chief of all giving you iron-sight leaning, making cover actually useful without implementing a cover mechanic).
The idea of an 'innovative' game is, to me, a flawed idea. A lot of games have something innovative about them, even something championed for being sterile and unoriginal like Call of Duty contains innovation somewhere, even if it's just something minor like a new way of doing rewards in multiplayer or something.
Of course, another argument would be as to why we put so much stock in innovation anyway. Innovation doesn't make a game good, nor does a lack of it make it bad. The real problem the industry has is believing repetition + expansion to be refinement (that is, doing the same thing again + extra stuff = a new release, rather than just doing the same thing again but better).
