I'm feeling I should contribute, as a thanks for the help I have had in the last couple of days.
Sadly, despite the fact I am in full time work and run a few websites, I still play video games a lot. It's not hindering my health or anything, but I need to cut way down on it.
I got a PSP for my birthday (which was on Friday) and one of the games was Liberty City Stories. I find it difficult to put the game down!
But my answer is around 4 hours, so I put 4-6.
