10 rounds with changed payoffs has some really interesting results.
Punishing cheating from both sides, regardless of how high, still leads to the cheaters taking over.
But if you increase the payoffs for both sides cooperating, even if it's just by +1, you already eliminate all the cheaters very quickly and even the copycats are gone pretty quick, leaving a population of only cooperate.
Sure that's for the 10 round game without any of the other players, it's still very interesting how even in that setting it seems more beneficial to reward good behavior vs punishing bad behavior.
