More Games for the Holiday Season

After checking out the Duke Nukem 3d give away I came across more offers on GOG.com, which is undoubtedly the intention. ArmA2 with Operation Arrowhead add-on, together called Combined Operations, is a necessity for playing the DayZ simulation zombie mod that's taken off big time. I've only watched a couple of game play videos so far but it looks real good. It's half price at $14.99 which is an acceptable starting point in my book.
Unfortunately it's Windows only but we'll see how the emulators keep up. If not, it may be time for that torrented XP.
Please let me know in the comments if you got any experience with running this on CrossOver, PlayOnLinux, Wine etc. Cheers ~ B.
