Very rarely during the week. I don't like short sessions, I want to play at least an hour or better two. It's mostly at the weekend, saturday evening/night. Sometimes a session on friday night, if I'm not to late at home (I have different working hours) and feel like I have enough energy left and maybe on sunday. I try to play as much as possible during holidays.
But it's always a struggle with all the other stuff I need and want to do. Of course there is the housework, and sometimes I want to watch a movie/series, and I'm following some gaming channels. So I have to decide what gets my precious free time.
In the end I'm playing not as often as I would love to, sometimes not for weeks, and there are so many games I'd love to play. Even if I can cross out some form my to do list, it's not getting any shorter. D:
