Soldier of Fortune, an awesome action game. W40k: DoW, specifically for local multiplayer. We were such noobs, but we had so much fun! Dota, I haven't played it in a while, but I kind of want to, but... it's a hassle. "Lemmings," it just doesn't work anymore. Original War, not the most well-known, but a truly masterful game. I should install it again in the coming days. I replayed the second System Shock half a year ago. Maybe I'll remember something else over time.
