It's not bad, I played it for ~ 3 months when it opened. Certainly not AC1-caliber, but it was a fun time for the period that I played. I'd say you might as well do the trial, you've got nothing to lose. I don't think it would be a game that you would be able to play for months and months, but the trial would at least be fun. Hell, any MMORPG free trial can be worth it, since most can be fun for at least a week.
