Football Manager 2005!
I doubt any of you play it, but I just felt like mentioning it anyway. I play various other games (The Elder Scrolls series, KOTOR series, various Paradox Interactive games, Madden, the GTA games, etc.) but there is only one game I always go back to, Football Manager (formerly Championship Manager...untill Sports Interactive (Football Manager) split with Edios who put out an amazingly crappy Championship Manager 5 last year).
In the game status area, it has a little bit with shows how long you've played that particular saved game...and my current game is 14 days, 22 hours, 50 minutes.

(*NOTE* Some of that is the game being up while I'm off eating, or taking a shower in the morning, or when I'm watching TV or something, so it's a bit more than the actual time I've spent playing it) and thats just in one saved game!

Which is now in...2012!
Even got a couple pics from the end of my last season as Tottenham (you can also see my spiffy city I created in Chrildren of the Nile)
Anyway, I don't expect there to be many football (i.e. soccer) fans here, but oh well...I'm bored. *nods*
