I really don't mind multiplayer games. I've played Wow almost 14 years. I also played TSO until Eaxis closed it down, and then EAland until that flopped and was closed down. A lot of people loved TSO, myself included.
Although, what did I do in the game? I joined a skill house as a hostess. I skilled (which you had to do constantly, because our skills decayed) and took care of other people's sims who also skilled. After they were done skilling, it was off to make money. That was what "most" people did in TSO. Thinking back on it, that was pretty boring game play and to be honest, today I'd expect more from an online multiplayer sims game. The fun in TSO was of course the contact and connection to other players. I met some pretty awesome people there (actually still have occasional contact with some), and wouldn't have missed it for the world.
I want the freedom to do whatever I want in my game, for my sims to be what I want them to be, do what I want when I want. I need freedom, and not depend on other simmers. I don't think that would be possible if Eaxis went the multiplayer route.
