I tend to find a freebie every few weeks to goof off on. If you don't mind the erp'ing or huge learning spike at about lvl 15 perfect world isn't that bad. (( it just was not my kind of game)).
There is also a star gate mmo in the works if your a sci fi fan. I have doubts for it's player base being such a unique genre but if it takes off I'll be on there as well as WAR and WoW (( after lich king is out..it's like pulling teeth to play it right now...WAR can not come soon enough))
Non-mmo, well I have the Wii for that. I have forced my son to add a ton of old school games to it. We have Street fighter 2 and King of monsters just to name two that I enjoy "schooling" him on.
I suppose if it came down to it you could play a ..dancer on FFXI. My wife says they are rather fun. I lost all respect for FFXI with that. When I posted on alla right before ToAU about possible jobs I made a joke about SE going off the deep end and giving us a dancer class...had I known of my prophetic powers :P I would have said berserker or Mime instead. (( or manthra))
Any way, I'll add what free game links I get when I get a chance. may be something you will like out of them.
Edit note:
Here's a steam tech beta I keep trying to get to work with out much luck.
