I think what's killing the game experience in general is the insane amount of money it takes to produce the games. How can someone afford to take a risk on an experimental game when the production alone is several million dollars? It's frankly too much risk because if they make a failure of a game, they lose several million from production, plus a second couple of million in advertising.
And since all game companies are corprate first, they see those dollar signs. If they don't know as a fact that they will make back their money, the game dies.
