My brother's an (EverSmack/EverCrack) addict, and I've just not gotten into MMORPGs. The only games that will STILL really get me going for long sessions are CivII (CivIII sucks) and SMAC. I was on a Tropico kick for a while, just off the Demo, and I recently got the Mucho Macho edition but have had no time to play it yet (7-3:30 shift is nuts, when you have to get up at 5 AM).
Online I've been a trivia junkie the last couple of months, but I think it's time to give THAT up as well.
