I am out of the MMO genre. I have given 7 years of my life to Everquest, in which 3 years I was guild leader of a raiding guild. I then moved to WoW beta/Live and spent 2 years into a raiding guild again.
These games are simply too good, too addictive. The companies will make everything to make sure you have to log on daily and keep you mindlessly grinding so they can receive your monthly fee. (hello raiding, hello honor system!)
Anyway, it feels really good now to actually buy a game, complete it! and sell it back (or keep it, depends on the replay value)
