I'm a sucker for medieval fantasy strategy games like Total Annihilation: Kingdoms. Give me a chance to build some farms and archery towers, train up an army and march out against a mob of goblins and orcs, and I'm good to go for quite a while (yeah, I know it's not exactly consistent with my "in favor of living" thing... heh).
Anyway, my latest game is Lord of the Rings: Battle for Middle Earth II (no, I haven't played part I). I'm not a hard-core gamer, and haven't gone in for the multi-player online mode, but I definitely enjoy spending the occasional hour building up big armies of elven archers (love the archers!) and doing battle against the forces of Mordor.
(I think it's because, in my head, I'm still 12 years old...)
(And speaking of ages, happy birthday to Jenna, who turns 5 today!)
