I started playing one hour ago, it's smooth and I totally feel playing Civilization ... on my phone ... with a free-software ! <3 I don't know yet how the game behave when we go further in time and that there is more stuff to deal with, but for the moment I'm totally impressed. One of the best apps on f-droid in my opinion!
Yes, I just tested it quickly on my Linux desktop : it works well and seems very good. I really like step by step assistance from the beginning of the game. I will enter it in the game base. Thank you!
