I prefer wow, and I enjoy it.
Last week I only played for a few hours on Sunday running random instances with my social guild (yes haters, there are guilds for SOCIALISING! You don't have to play 3 hours a day to be in a guild).
Sometimes when I'm in the mood I can play for a good few hours a day for a few days in a row, but like last week I didn't fancy it, so didn't play it much. No one forces me to play it, I have free will unlike the haters that are abundant on the forums that can't control themselves or just like to make up horror stories based on the choices of others
I do suggest the free trial, although I would say the first few weeks of levelling (well..depends how fast you level, I was slow) is very boring.. but it picks up
Exercise some control, and there is no way to get addicted
Send me a pm if you want some more information or an invite to the game
