Games that just missed the list.
Perfect World - Was a great game with a lot of cool features. The game had a great system behind it with cool skills, great graphics, amazing customization, and cool boss monsters to fight with your guild. As well as great combat in territory wars and all of that good stuff. It was just way to generic, lagged to much, the company was terrible with updates and news, and it was bad for new users. Until you grinded your way up to the mid-30's through killing the same monsters for five levels, or doing the incredibly boring quests, the game was wayy too boring to be played by most.
Hellgate London - The game was fun, and even though it disappointed a lot of gamers it was still pretty refreshing for the gameplay it had. Didn't really impress me though, and a lot of gamers felt the same way.
Ghost Online - A well-made clone of Maplestory, as so many would claim. But the game was different, better actually. The game had some really fun player vs. player in it, that made it up to your skill level, not your character level. It also had fishing and cool monsters. If the company had done a better job and built up the community so that more then fifty people were online at any time, it would have been great. Was also pretty grindy, but that's the same way Maplestory is and it's good because it provides a challenge to get to the top of the rankings.

"Wow, with all of those MMOGs up there, they all sound so great! How could last year possible have been such a terrible year for MMOGs if it contained all of those great games?"
Well, the answer is simple. Disappointments. This year was the year of disappointments in the MMOG industry. There was so many that I find it hard finding a place to begin my list with. But first, this is what I mean by a disappointment in the industry; A lot of games that were announced attracted huge amount of hype. These games had forums covered in numerous threads about the game, when it would be out, where to download the client, yeah, you get the picture. Then when the game came out, the threads returned. But this time, they all were angry threads, about how the game was so generic, so boring, so grindy, so crappy, whatever lame reasons people could find to insult the game.
