Redspyder: As long as they're intending to stick with 1UPT (1 unit per tile) , I won't be buying. Which is a profound pity, says this long-time Firaxis fan whose first Firaxis purchase was a new copy of Civ1 (yes, I'm old) and who has bought all the products up to Civ5. Civ5 I played a few times and found utterly repulsive, because of the 1UPT (Dale of Civ modding fame and several others have gone into detail as to how 1UPT affected all the other design decisions -- negatively). I nearly fainted when I heard abotu Beyond Earth -- then I swore mightily when I read the lead dev's comment that he likes 1UPT and will be sticking with it.
Oh, well. I'm content playing Alpha Centauri and heavily-modded Civ 3 and Civ 4. (Hell, Civ2 is still on my hard drive).
May I ask why you dislike it so much?
One of the reasons that I strongly prefer Civ 5 to 4 is the 1UPT rule and the removal of 4's doomstacks. It's a feature that I think works well with a hex-based system (I wouldn't use it with a grid layout). I felt like the removal of doomstacks added more complexity in unit choice and placement.
Of course, I shouldn't overstate its importance either way, since SMAC is an amazing 4x game, and I was never bothered by unit stacking there. I think SMAC balances it a little better. Other approaches I've heard are concepts like allowing multiple units per tile but having some sort of supply/logistic requirement to hold multiple ones.
A little more on topic: I haven't been too impressed by Beyond Earth. I guess I was hoping for something with as strong a personality and an interesting setting/story like Alpha Centauri. Nothing's really grabbing me right now. Of course, judging a 4x game isn't best done from a few youtube videos, so I'll still keep an eye on it.
