I had Beyond Earth on for a half an hour or so.
My first impressions: The UI looks unfinished and bare, and for some reason I didn't get this sense that we were on a strange new planet, like with Alpha Centauri. With Beyond Earth it just feels like I'm sitting in front of a gaming board, like RISK, rather than an actual world that exists out there somewhere. I'm not sure why that is exactly, but I found it very hard to immerse myself in the environment. With some civ games, "it just sort of happens". With this one, it didn't.
It also feels weird to see all the Asians (for example) grouped as a playable entity.. That seems maybe a bit.. unrealistic? too simple.. If we end up on another planet, there's no way the Japanese, Chinese, Indians, Kazakhstanis, Pakistanis, Afghans, and Indonesians will all join hands and sing kumbaya as they're launched into space. I'm not sure what other playable camps exist in the game, the other one I saw was South America. That's a bit more believable, but I still don't buy it. I think people are far more likely to organize themselves along purely ideological or religious or even nationalist lines, rather than what this game is trying to push. It feels very artificial.
So.. those are my first impressions. I am going to try to have another go at it sometime this week.
