As a Brit, I'm rather obsessed by football (Soccer to Americans but as we use our feet to kick the ball instead of our hands to throw it, we'll call it football) which means any football game that's released automatically has my attention. Sounds incredibly boring to the neutral but Football Manager is a series which you take control of a team and do your darn best to lead them to glory. You don't get to actually play the games so it's pretty close to being entirely text based but it's a thrill nonetheless.
Just checked my Steam account and I've currently amassed 936 hours in Football Manager 2012 which is like playing for 39 days straight. Quite shameful but we all have our guilty pleasures right?
So what game have you sunk the most time into?
