I’m going to keep this thread updated with various deals on Quake 3 I come across. Let me know if you see any others.
Quake 3: Arena + Team Arena is at regular price on gog.com ($15)
Quake 3: Arena + Team Arena are at regular price on Steam ($15) http://store.steampowered.com/app/2200/Quake_III_Arena/
Aww, missed it! Well, I already have it on Steam, so there's not much of a reason for me to get it on gog other to support DRM-free platforms and I think I'd rather donate to OpenArena because Id Software isn't Id Software anymore...
Will update this thread again when I find another deal.
Updated with Humble Bundle Black Friday deal
Updated with Steam's deal.
Updated with gog deal
