I still haven't really been able to make the jump from Civ 5 to Civ:BE. BE's civ and tech choices somehow manage to feel painfully samey and confusingly unorganized all at the same time.
I was super excited for it, but I couldn't get into the future tech tree.
It was hard to determine what tech to reasearch and if I needed "whatever" what tech to research, since I didn't have any historical reference to draw from.
Also one of the new victory conditions was difficult to keep track of and kept sneaking up on me multiple times.
Civ:BE is an unfocused mess.
