Ugh, not this thread again. Why do people keep thinking the "solution" to MMOs is different content for different players? It's not. T_T What players are really satisfied by is feeling that the game is telling them a story focused on them, but that isn't actually related to whether the player is given different random stimulus than another player, and is absolutely not helped by limiting later players' opportunities because earlier players have already used them up. If anything it should be the other way around, players need protection against other players screwing up the story the game is telling them about their character's adventures.
The solution to MMOs is to separate boring themepark WOW clones from actual MMOs. If you have to call MMOs VOWs or something w/e. The label is not important except in conveying the idea, which is the main thing.
If you want a game to tell you a story you shouldn't be playing something prefixed with massively multiplayer. That's just the stupidest thing ever.
Whether or not there are a large amount of people who want to play a REAL MMO is a whole other question from the idealized concept of the games. EVE Online and ATITD both work well are are incredibly social compared to themeparks.
I get that you love JRPGs and what not but not everyone does and jrpgs have very specific rules that are anathema to massively multiplayer game play.
