There are days when I get bored and start up a game that I finished quite some time ago. However there are games that once I start them I absolutely have to finish them. Don't know what it is, but for some reason I get an itch that I have to scratch where I have to finish the game. Are there any games that are like this for you?
An example of this for me is when WoW was down for some maintenance I started up Red Faction Guerrilla and then after 2 to 3hrs passed I put it down to go play WoW since the servers were up. However I got the itch to finish what I started and played it all the way through to the last stage.
