"Knock WOW off it's perch" - All i can say is that it's true.
People don't neccessarily play the best games out there.
WOW is awful, yet it has a lot of people playing it (and moaning about it).
Blizzard have done a hell of a job getting so many people to play a sub-standard game, my respect goes to them over the marketing.
It certainly doen't go to them with regards the game they have created...
As far as I can tell the majority of the new MMORPG's are following much of the same system, with levels.
I need to do some reading up, but whichever MMORPG hits market first where they don't use levels and that you increase your skill by using it and are forced to use it against/on harder/higher creatures/resources as the skill goes up (a la UO) will be the first to get my money.
The level chasing games get boring quickly as everyone rushes off to get to the maximum level as quickly as possible.
