Daily sims on Saturdays and Sundays.
I know that the majority of users come from the US ... but for me as a European user it's frustrating not to have any sims during the daytime at least on the week-ends.
So I get a few hours after work (of course I can't head to the computer right after I return home, at least not if I want my marriage to last longer than the current version of OOTP
), and when I get up Saturday morning the sims are done and there's nothing to do except checking the Aution House before they start again at 4 p.m. local time.
I fully understand that sims can't run 24/7, but having sims during the daytime at least on Saturdays and Sundays would be nice for us in Europe.
