Only the original for us.
Yeah a lot prefer the originals, and I have all 3, but I prefer SupCom 2 myself. Haven't got any of them installed at the moment but might have to again soon. Probably my favorite RTS.
We do coop mainly but versing each other is entertaining when we do do it.
Is a couple of maps in SupCom 2 that really allow for a onesided battle (as in placed out well for 3 vs 1 etc) Playing against a cheating AI is pretty fun coop like that
Wish the game used multiple cores though, in long games the AI slowly causes the game to slow to a crawl, 1 in-game second turns into 4 IRL, at that stage we just quit.
Ha yeah it can bring a system to its knees
