Im quite surprised that no one else has said this (or Im too lazy to find it ) but Shamus has pretty much just described EVE online. They even use the whole 'playground' analogy for themselves. (Linky: http://wiki.eveonline.com/en/wiki/About_EVE_Online)
Progressing (or leveling) in EVE is all done in real time, so it may come across as a barrier at some early stages it actually ensures that you are ALWAYS progressing - rather than being based on how quickly you can grind quests etc.
Obviously its not the only thing needed to progress - money is the lifeblood of Eve. I won't bore you with the different ways but there are lots - which is supposed to keep it interesting. Bored playing on the swings all day? Play on something else? In something like WoW if you DON'T raid you can't progress (because you wont get the best loot) but in Eve you always progress regardless and its a choice on how you spend your time rather than feeling like your being pushed into a single activitiy.
Personally I see the main problem is MMO's is that they either try to satisfy too many or too few people / play types. If its done too thinly (ie, SWG) then you end up with alot of different game mechanics which are as deep as a tea spoon. Something like WoW is designed for the 'killer' playtype - everything else is an accessary to killing. Crafting gives you more money so you can buy stuff to kill easier - questing provides XP so you can kill stuff easier etc etc. This means that although the game machanics for killing and grouping are quite excellent, without much variation it gets boring very quickly. It also means that very little attention is paid to the players or lore / RP because most are completely focused on getting the 'lewt' and everyone else in the party is an expendable assest to help them get what they want.
I don't think that any MMO will be perfect and alot of the time its down to the players. If you give people a playground some will love creating new games to play with the equipment with friends and have alot of fun. Others will see just the bland equipment that will be used to destruction and cast out once the fun has exhausted and expect something new and different because they can't create the fun themselves with the tools provided.
