To be honest i totally agree with him, even if he didn´t play the game.
The thing is that TSW was/is a pure “Themepark”-MMORPG. These games only survive with a steady flow of content because there are almost no Sandbox-Elements and you need a big team and lots of money behind that kind of Story-focussed games for them to have a future, because nearly EVERYTHING you can do in the game as a player has to to be created by the developers!
Story, Quests, Dungeons, PVP, Scenarios, Endgame etc. … you name it.
Funcom is not Blizzard, Bioware or whoever. EA also was only the publisher.
So looking backwards I have to agree that nerdslayer is right.
(And yes … i didn´t realized that when i was playing the game myself in the past)
If there wouldn´t have been PVP for example I would have stopped playing very soon after the ending of the story, wating for it to continue, because i don´t RP, wich is always a way to to create your own content. But not every player likes RP, like not every player likes PVP or Dungeons or Scenarios etc.
So yes, it was indeed doomed.
