I don't see myself playing another MMO anytime soon. I played WOW for 6 years. Cataclysm killed it for me. Pandas were not enough to bring me back.
I may give Skyrim Online....I mean Elder Scrolls Online when a shot when it comes out.
I did briefly play FFXI but it was not solo friendly and the only people that were ever online seemed to be Japanese and several levels above so it was hard to find help for the things I needed a group for.
I hope this new FF online isn't like that.
