"new, innovative and breakout games".. you jest, right?
While I love my PC & console gaming "innovation" is not the first thing that comes to mind when I think of my favourite past-time.
Rather I think of evolutionary, predictable, safe and derivative. When you have $50m to spend on developing a game, do you go balls-to-the-wall different or do you play it safe by pandering to the established market and expectations?
If your budget is, say, $50k you can push the boundaries a lot more. IMHO, the casual games show far more innovation than the old skool AAA titles generally do.
One thing I will grant you: big "hardcore" titles *do* push technology limits in terms of graphics, sound and physics.
