Unironically calling yourself a "consumer". Assuming crunch means the game won't still come out broken. This post is so clown shoes I wanna cry a little.
Also, to answer your question, the alternative is delay the game to a reasonable date so that the devs dont have to work more than at most 50 hours a week. The downside to this is that some rich dickheads in suits are going to get slightly less of an initial return on their investments so instead, just grind those devs into dust. Besides, there's plenty of new employees we can crunch waiting to replace them and they will absolutely never go away. This is a completely sustainable industry!
