The Beta isn't a free play thing, they give you something to look at you write a review, E.G, You may be asked to create a bunch of characters, or do lots of run throughs on one quest - they on't let you just run out and do a campaign,
Yeah, but any decent developer does not stop players from creating guilds and testing that part of the content as well. I am currently in an Alpha test for different MMO, can't say which one NDA, and in that game we have a guild for alpha testers to join and discuss problems, possible fixes, etc and the developer fully supports these activities. Yes I know all about how foucused testing is now days compared to back when I beta tested Ultima Online however you are still allowed to test ALL aspects of the game reguardless of the tests focus.
