M-F, after work, it gets turned on @ 6:00-8:00 depending on errands, dinner, etc. But I usually eat dinner playing. And then turn it off 11:00-12:00. So short sessions for me during the week, only 4-6 hours. Weekends though, computer gets turned on as soon as I get up 7-9 and Sims pretty soon after that, then I play all day with a few breaks for necessary stuff (I just save and pause) and don't stop playing til 1 or 2 a.m, sometimes later. Unless of course we have to go and actually DO something that day. Longest session, I'd guess, is probably @ 14-16 hours, but if I've got a new expansion, or neighborhood, watch out! My husband doesn't call me a Simaniac for nothing.
