If you liked Tropico 3 then you'll like this game. It is more of the same but with a slightly different GUI, different levels and some more building and political options. I wouldn't pay full price for it but it is good fun.

I take back anything good I said about this game. It is completely different to Civ 4 in all the wrong ways. It is ok for playing with new tactics but that is about it.
Loved the first 4 but I just dont find Civ V fun.

A modern classic that is still being developed so the gameplay is ever changing. Ignore the hat fetish that the majority of players have though. That is just weird.
