if you ask me, the industry has changed, it's just that the publishers that are blind and keep chasing that crowd. seriously, how many recent shooter with this generic gritty artstyle actually sell? most of the time we heard news of bomba, you'd think those would serve as a warning sign for publishers to change things up.
How many games actually sell? The high sellers last month were what, 200K? 400K before that? The industry is on a decline, and it'd wager it has more to do with high priced consoles and games and a shitty economy. People buy a few MP games a year and call it quits.
I agree things need to change, but I don't think it's on the end of developers. Publishers need to lower game prices and Sony/MS/Nintendo need to drop the price of their console hardware. Another high tech expensive generation will do a shit ton of damage to the industry.
