So yeah, it's a game of many contradictions. But worry not-- you can try the game out yourself right now by downloading the hefty 1.4gb demo over at Worthplaying, GameDaily (disclaimer: AOL owns GameDaily, and they also own Weblogs, Inc, which owns Massively) or FileShack (shudder-- FileShack and I do not have a good history). KillTenRats says the demo lets you play as a Blademaster or Marksman, and that it'll take you through part of Act 1. He also hears that the demo is singleplayer only, so any big MMO elements will probably have to wait until the game is released.
And the good news is that that's not too long a wait-- we should see Hellgate: London in North America on October 31st. Let us know what you think of the demo.
