Do you know of other games similar to Catan?
Im not sure of similar ones , however i know they have a virtual game now for catan not just a board game anymore
A virtual Catan game might be fun to play someday.  Right now I have a household of family members always eager to play.  I like that even the youngest can fairly competently challenge their older siblings.
Stratego as well as axis & allies have been put in the top 100 family board games by better homes and garden magizines. Have you tried them?
I have played Stratego a few times.  One of my sons really enjoys this game and plays with his friends.  I have not heard of Axis & Allies. Now that it is summer vacation it might be time to explore a new game. I admit that I like the generally peaceful nature of Catan.  Anyone have any sheep? ha ha.
Now that its summer and everyones wants to be outside, a frozen t shirt race would be a fun family game to play outdoors. 
That would be fun and funny!  Have you tried it? we went from very cool weather to extremely hot and humid.  A frozen shirt race and popsicles and a barbecue, followed by some inside downtime with a board game might be in order for this Memorial Day weekend.
That sounds like an amazing family memorial day weekend! Yes i have played it before and its just as much funny as it is fun.
Do you have Memorial Day plans? We used to go to a lake house that was stocked with, among other amusements, board games!  But this year we are staying closer to home.
Ill just be barbqueing with family and possibly going to riverview park near me for firework and to watch soe local bands play.
Isn't it wonderful that bands are able to play in public again.  We have several concerts in the park all summer long.  It is a very eclectic list of bands, so there is something for pretty much anyong
