I've posted on another thread about MP incorporation. So I'll keep it brief here.
I'd pay hard cash for a MP release of some kind.
Collective turn system (all take turn 1 at the same time, then all move to 2)
Do not 'balance' things for MP. We really don't need to change the stats for MP.
Don't remove the fluff. People who play this do so because of the detail and depth.
I'll be playing on a LAN with friends or my brother. I see no need for a matching type service for joining games. I too bought the game thinking it was already MP. All I would like is a 'host/join' game button and the ability to save MP games to resume after sleep
Please, Stardock, strongly consider a MP release.
P.S. As for all those people complaining that the anti-MP people shouldn't have to pay for a MP addon; well that's just stupid. If you don't buy the MP addon, you're not paying are you? There's no subscription for this game, so you're not paying per month for new features. If you like GC2 as it is now, why do you care if others play MP with a patch that they've paid for?
