Quests are a big part of every RPG, and they'll matter in Hellgate: London as well, of course. That being said, Hellgate:London is an action RPG, and isn't totally quest-dominated. You can just go out and kill monsters if you want to, and thanks to the random level layouts, you'll have fun doing so in different ways. Lots of RPGs are fun when you first start, but boring to replay since everything unfolds exactly as it did the first time. That shouldn't be a problem with Hellgate: London, since as was true with Diablo and Diablo II, replayability is one of the major priorities of the design team. They want you to play through their game over and over again, and while you may enjoy doing the quests, you may not want to bother.
