So I'm planning to have a LAN party. There will be a couple newer macs and some PCs. What games are compatible? The older and more nostalgic the better. I was hoping for Doom or Quake. Command and conquer. Maybe Warcraft 3. Unreal Tournament and original Starcraft. Any of these work? I will not have Bootcamp. Is there anything I should know? Everything updated and will difference in XP, 7 or 8 matter? I want this to be epic.
