I Really wish more of my friends were into board games. I'd love to play more of them and more regularly.
Axis & Allies is awesome, as is Settlers of Catan. I haven't played the other ones you mentioned, but I've seen Risk 2210 and it looked interesting.
There's a game that has been sitting in our basement for some time that I've always wanted to play but I can never find anyone to try it out with me. It's called
Supremacy and the impression I get is that it's sort of like Risk on crack. But I've never played it, so I don't know!
Oh, other games by Gamemaster are good too. We have Fortress America which is a decently fun game, but definitely not as cool as Axis & Allies. I'd really like to play Shogun sometime too.
