That’s a cool sounding game.
What would add an extra dimension to it is the ability to disallow trades with AI’s.
While it is a nifty trick to attempt (doesn’t always work) to trade tech with the AI’s, it does reward the folks who can login right after a turn … and/or delay submitting to do this … but can’t blame 'em.
Probably nice to leave this ability in the game, but maybe Jay in his copious spare time (!) can add an option at game creation to optionally disable tech trading with AI’s … both “robots” from the start and players that AFK.
I can especially seeing that being a nice option for the game you have in mind above … and HEY, if you decide to do turn-based, let me know as I’d love to play.
