I quest for people so if you consider that to be playing than so be it. I picked a 3-4 days a week but that's not precise. It's only when I feel like questing that I do it which sometimes goes everyday or 3-4 days a week especially now that school began again. Can't be fussed playing RuneScape for days instead of chilling with my friends and stuff.
I don't personally play on my account though, only on others.
