I'm going to say this: if Gendo follows through on his threat to deny Calamitas points, I'll do Gendo a solid in the future. Not sure in what form, and I'm open to suggestions, but at the very least any "I can screw over player A or player B" decisions from me will break in Gendo's favor.
Nothing against Calamitas, but I'm opposed to winning the game under threat of "well I'm going all in, so either I win or we both lose" and it going to a particular person because they got there first.
And the way to defeat that kind of strategy is cooperation.
This isn't a 0 sum game, but there is a winner. I don't think we're going to be able to make it a perfect tie, nor do I think that's ever going to be in the interests of a majority of people. But I'm going to try to reward people screwing up the strategies that create runaway winners.
And yeah, the social aspect of this is really interesting too. We aren't going to act perfectly randomly or all obey whatever the equilibrium strategy is in any given game, and that's fascinating.
