The next expansion in the Guild Wars series, Nightfall, is just around the corner -- but for anyone who can't wait until October, NCsoft are running an open preview event on September 22-24. During that weekend, Nightfall will be free to play for just about anyone, regardless of whether you have Guild Wars already.

The previous expansion, Factions, had a very successful preview event, so it's no surprise the idea's being repeated. It makes sense for NCsoft to capitalise on Guild Wars' free nature by, well, making it even freer -- if only for a short while. Those of us already resigned to paying monthly for MMOs may find it a nice change to try a new one without cost, but as every hour spent on a free game is one that we have already paid for on another MMO, it's hard to drag us away.
