We gave you a brief rundown on how Civilization World, the upcoming Facebook version of the classic PC strategy series, worked the other day. Now you can see for yourself in this trailer.

Those expecting the same game, only running in a browser with a Facebook logo on the top, will be sorely disappointed. Those hoping the more casual medium would let them try something a little more collaborative, well, the idea of co-operative "nations" sounds pretty cool.

Civ World will hopefully be out this Summer.
