Favorite low complexity, High depth games?
I am more into board games than any of my friends. I don't get to play that often which means I generally have to play games that are easy to teach with simple mechanics that anyone can grasp the first time they play.
Unfortunately most of these board games I find boring and have limited replay value.
I would love to find more games that have tons of ways to use simple mechanics to build really complex strategies that keep the game engaging play over play.
I think one great example of this is 7 Wonders.
What are your favorites?
Edit: other personal preferences are that it can be played with up to 4 players, and is still good with 2, also is less than 90 minutes long. I also always play to win but not everyone in my group does. So bonus points if you can play to maximize fun (still enjoy the game even if playing poorly)
