One of the best games for me lately is anything Harvest Moon; the zen of it is a HUGE stress reliever out here in the nowheres.
Yes, Harvest Moon, Farmville on crack. Stop judging me. STAHP I CAN FEEL THE JUDGEMENT.
Otherwise, I'm replaying Pokemon Soul Silver, Fallout New Vegas on my PC, and the old PS Spyro games also on my PC. Because emulators are awesome.
(caveat: I'm not advocating downloading the roms if you don't own a hard copy of them.)
Also minecraft when I'm in the mood. I go through phases of each game- I'll play one for a few weeks on my off time and rotate them out casually.
