I have never played a Stonemaier game. Why? Because I don't like bots, dummies and automata. I always prefer to play against the game itself, face the integrated enemy, not an opponent who mimics my moves. But the integrated enemy is in fact a bot, I hear you say. Well, I never said I was right, and I didn't ask for a dialogue.
But really, why doesn't Jamey Stegmaier try a cooperative design?
a) Because he thinks cooperative games are not games, they are puzzles. He is one of those people who give all coops a rating of 1.
b) Because the Automa Factory would close down. Strikes would ensue.
c) He has talked about this in his designer diaries. You have not been paying attention.
Indeed, I almost never read designer diaries.
