I'm currently addicted to finishing off Portrait of Ruin and PW3 and I've been playing Element whenever I've got a spare 10 mins to fill so it's more like 2-3 hours a day right now, but normally I'd play for 1 hour before going to bed. Completely unpredictable at weekends, depending on what I do sunday afternoon sometimes I'll spend hours on it, other weekends I don't touch it at all.
