Considering I work full time and am constantly traveling, I really wouldn't have time for it anyway.
What's full time where you live? Over here that's just 40 a week, leaving us with 128 hours for travel, eating, sleeping, and doing whatever we feel like.
40 hours. But like I said, I travel for my job, so I'm almost always gone Monday through Friday afternoon. I have some time on the weekends, but that's mostly reserved for doing house and yard work and spending time with my family. So it's difficult to invest huge amounts of hours into anything like an MMORPG for PS3.
