Check our review of the new expansion to 7 wonders, Armada. You can find it in the review section. The review assumes you have played 7w before.
For you who might have stumbled in here without knowing what 7w is, we can tell you this much; It's not Risk, it's not Clue, it's certainly not Monopoly. 7 wonders is actually a game worth playing.
It's a cardgame that plays for about 30 minutes, even with 7 players, and at the same time has alot of deph. It's simply amazing, so do yourself a favour and go buy it.
