Alright so last night me and my friends attempted to play BE. My first impressions are that the game has been changed enough that an experienced Civ 5 player will not know what they are doing. Sure there are workers, farms etc.. But enough new mechanics to make the game very confusing. Which IMO is a good thing. This means it's not just Civ 5 with a new skin. So far it seems that trade routes are extremely strong, the behavior of the aliens is very unpredictable and the tech web incomprehensible. You really have no idea if an alien is going to attack or do nothing. It's strange because I'm used to barbs always being an annoyance. They will wander about your borders, enter your territory and not even pillage or take a worker. Health seems to be my biggest issue in this game. I went to -15 pretty quickly and was unable to figure out how to get health buildings because the tech tree is insane AND techs seem to progress very slowly. We attempted 3 MP games and they all ended with crashes before anything interesting happened in the game. There's my 2 cents for what it's worth.
