What game, board, card, or console/pc have you sunk the most time in?

6. lately, World of Warcraft

I play several hours a day, and have for a year or more.

I used to play the hell out of Civ 2's One City Challenge. That's where you play on Deity level, and can only ever have one city. I'd regularly win by the early 19th century. Fun!

For a couple of years, it was Magic. I quit when they started releasing seriously broken cards, plus the tourneys I was going to interfered with visitation with my daughter.

Tabletop: Battletech

No one board game dominates now, as I have several German board games that we rotate through. Power Grid is my favourite, but we also play Power Grid: Factory Manager, Agricola, Puerto Rico, and Settlers of Cataan, among others.

On the PS3, it's a tossup between the Assassin's Creed games and the God of War series.
