Holy crap, I think I find myself agreeing with Beatdown.
Take those 2 months or so in EQ between level 50 and the planes opening up. You could not imagine all the crazy stuff I did to entertain myself because the engine let me.
It's all about what you are capable of coming up with, not what is spoonfed to you by the devs. That's another thing I dislike about WoW. Whenever something new comes out in a patch, they tell you what you have to do IN GREAT DETAIL rather than let you have at it.
I like to use my brain to come up with my own solution, but I find WoW too restrictive for my style (too well-tested, contrived, constricive). It's subtle, and most people don't know any better anyway, so they don't care.
