What's your favorite video game/game series of all time? Console, PC, whatever.
I have two favorites: the Thief and Civ. The civ series has endless replayability and, in its latest incarnation, a good balance of strategic choices to make. Plus, it's fun to watch your civ evolve from a band of settlers to a huge empire. Thief has the excitement of slinking through the shadows while enemies walk by completely unaware, and the fun of sneaking up behind someone and knocking them out

And then there's the Shalesbridge Crade level in Deadly Shadows

Not one to play before bedtime!
