Civilization 5 (65h) - Steam clocked it at 80h, but there were a couple of times when Cameron had been playing as well as times when I'd left it on. Completing the Deity difficulty level took up the most of it. Currently I'm attempting an emperor 1-city challenge as the Indians. Culture victory still looks a fair way off and Montezuma and alexander are >10 cities, but I'm more or less winning the tech race.
I've also started fiddling with the modding tools. Tried at first to fix the wonder placement, but it doesn't look like it's in the XML or Lua scripts. Next up is to build a 'Conquer Australia' mod where everyone starts on a boat in 1770. AI and happiness mods to follow if it's successful.
League of Legends (6h) - Couple of big sessions. Keep going back to Rammus for high level play. Should really be looking at other chars.
Bejewelled Blitz (5h) - Couple of large scores to show for the time investment, but really just looking at the phychology behind the game and its interaction with your social graph. Once again the highscore table is king when it comes to getting me interested in repeat play...
Dwarf Fortress (2h) - about 25 pop now, but still no caravans. Tempted to dig deeper to open up any caves I find.
