We love this game.  Interesting enough for adults, easy enough for a 10-year old to pick it right up.  I can't count how many times we've played it since buying it earlier this year.  If you're new to strategy games, this is a good place to start.  I look forward to purchasing the expansion boards soon.  I do wish there were a way to vary the game if you're playing with the same people over and over (you catch on to one another's strategies pretty quickly), but the main way to keep it interesting is to play with different players.  I've played with all ages, anywhere from 2 to 6 players.  It's been fun every time.
