One of the nice things about WoW is the challenge level is up to you. You can stay out of the tougher areas until suitably powerful. And it really isn't like a shooter that requires reflexes and co-ordination. I say this as one without either... ;)

Also you can have fun crafting and selling items or working the auction market like a daytrader. I played for 5 years and the last year I only logged on occasionally to see how my trades were doing.
