Is this going to be worth it?
depends. As far as I can see, the game is a normal single player RPG quest, with online PvP...
The storyline is single player driven, you can get help from friends, and help friends, but what I read last time, it is you doing a quest, not we or us. Most of the story content is very instanced. The main draw is the three factions and the constant battle for superiority. I do not like PvP, so this did not excite me much at all. This may have changed, though, it was over half a year ago I read the article, and it was very much still in concept stages.
That's not so bad. It sounds almost like co-op, which I love, so maybe they won't entirely ruin it.
