I guess it is somewhat subjective and maybe you could consider some of the list to be good games, but the overall point still remains. There is a huge list of what many would consider to be failed MMO's, I tried to pick a few of the ones that most would at least be familiar with.
And Jesus fuck, don't go pulling the WOW numbers shit. A game doesn't need millions of subs in order to be successful in fact I would rather MMO's focus more on a niche market, and try to maintain a few hundred thousand, and be good at what it does. I don't want a game to try and appeal to every fucking person in the world and in turn have to dumb it down to +gooder and pokemon like WOW does.
I also don't want a bland sack of shit like TESO either. You know as well as I what people really would like from this game is an MMO Skyrim not what it is.
