I've not seen anything here about Hellgate London, but it seem's to have a real part of MMO inside.
I give you the link to a Bill Roper's interview with this statement : http://www.shacknews.com/extras/2007/011007_roper_hellgate_1.x
Everything in this interview seem really interresting to me with lot of new things never seen in an MMO. So I let you read this article and do some comment about it. When I saw some game in the general game list here, I definitively think that HellGate London must have is place here at MMORPG.COM...
