You must live on the first floor.
I play mostly SP, though I do occasionally enjoy a nice hotseat game. Age of Wonders: Shadow Magic is also good for hotseat games.
Even though I've been rather curious about trying more serious mp, I'm somewhat anxious about normal pbem because it essentially forces you to play once a day or once every other day. By having such a necessary schedule, I feel like it might take the fun out of it for me. (Sometimes I feel like playing for 6 hours straight, sometimes not at all for the whole week.) Perhaps one day my curiousity will overcome my trepidation.
