Yes, because I do not have 1 hour 20 minutes a day to play in. I much preferred systems that let you do X number in a week or whatever as I could knock them all out when I was able to log in for longer blocks of time. Requiring a lot of shortish blocks is never going to happen for me.
Why would I want to pay $15 a month to participate in real life? I already have one of those. Games should be an escape/diversion from that.
