I honestly don't know, I don't play daily or anything... it's kinda random. Sometimes I'll go a week or two without playing anything, and sometimes I'll pick up my DS for an hour or so every day.
I end up playing games maybe 1 day a week if that for maybe an hour at max. Some times up to like 4 hours but that is rare like once every couple months that I play 4 hours in a single day.
Often, as much as 6 hours at a time, so at least 8 a day on my days off... I manage to get in at least two hours on days when I do work, usually. If I'm not gaming, I'm programming, building circuits, or fabricating something out of whatever scrap parts I have lying around... always nerding it up
I don't play video games every day. However, when I do become involved in a particularly engrossing game experience, I generally play for 15 - 18 hours in a row.
