I'm a big fan of The Longest Journey, so it doesn't surprise me that I'm enjoying DreamFall: The Longest Journey - picks up a decade or so after the original - just starting to get into it...
Looking forward to Half-Life 2: Episode One hitting Valve's Steam distribution mechanism tomorrow - playing HL2 (and Doom 3) were the primary reasons I built my Big Honking Box at home ;-).
Completely addicted to Zuma - this game was MADE to be played on the TabletPC (I'm testing out one of the Toshiba M400 Centrino Duo (dual core) TabletPC models - nice little machine)...
Might check out Call of Cthulu at some point, but have to make it through Halo 2 (yep, that's just embarrassing), Call of Duty 2, Resurrection of Evil (D3 add-on) first...
What are you folks playing?
