Sorry, why can't we complain?

Because every other game has bugs? That's insane logic. You are saying that because an industry has bad standards, nobody should try and change them.

Because it's just a game? It's a game we gave our money for, so it's the same as any other faulty/defective good. I fail to see why people put games on a pedestal as being unworthy of complaint when compared to other consumer goods.

Nobody forced me to buy the game? True, nobody did. Nobody forced you to buy a car, so if it doesn't work do you sit and take it?
