Which brings us to MMO's and why cheap blade and soul gold could be an extremely popular game. It's unfortunate this will get so disagreed with by the people reading this forum, but the reason most MMO's have failed like they have, is because they have released the same game over and over again with nothing to distinguish themselves enough from the already popular MMO's out there.
There has literally been NOTHING that they offer besides a different environment to run around in, that other games haven't already done smoother, more polished and BETTER, with years of content and features to top it off with, and if you truly look at the scene, you will see the most failed games are the ones that have done exactly that, the ones that have failed to find their own niche or reason to play it over something else. Of course, failures like Lord of the Rings online, Age of Conan, Rift, SWTOR, etc.
They have their own little crowd, people like it, some people play it for the lore, they like the idea of playing in that world, the simple PvE, whatever other features the game has that few players are looking for, these players will play it, but many of these games get either shut down and forgotten about, receive no updates and have a very small playerbase if they don't deliver in the way I'm talking about here, I'm talking about MASS appeal, the really popular games and what makes them so popular.
