The most unethical game ever!

I definitely fall into the infinity trap, myself, but that's mostly because editing/polish is much less fun than design iteration.

Based on your writings here and elsewhere, I have a suspicion this belief about playtest ethics is undermining you, and you'd be better off untangling and discarding it. But I'm also pretty sure you see some higher value to it even where its utility is questionable, so carry on!
