Civilization V is one of my favorite turn-based strategy games out there. I love the fact that you can build your own country and even build weapons and send satellites into space! I especially enjoy the improved graphics from previous editions. I like how the game also has so much more technology for each civilzation.
Granted I played with four people so my opinion may be skewed, but I felt the whole process took very long. We would set our moves, and sometimes the load times would take a few minutes before anything even happened. This caused us to get a little bored, and messed up the experience a bit.
