If you want to try out a upcoming MMORPG for free you can sign up to participate in the Guild Wars - E3 for Everyone event.
The folks behind Guild Wars will be demoing the game at E3 this month and rather than leave all of us who can’t attend E3 out of the fun they’ve decided to open it up to everyone during the May 12 to 14th event. Just download the client and sign up for a test account at the link above and you can try it out for yourself come the 12th.
I’m not too up on just what the game offers, but it sure do look purty.
