I bought it and now I can't stop playing it.
Its really fun and has a good story line.
The only thing I don't like about it though is that you need over 500 ram to play, and no one hardly ever talks to me ingame or wants to party with me :'(
I did not like hellgate at all. Found it kind of boring actually. Can't quite put my finger on exactly what I disliked though, it was more of an overall disappointment with the game.
