I have been playing it for a while now and it really is fun

If you're into hack and slash, you really should check it out. It doesn't bring much new to the table, but the stuff it does, it does right. And it's in open beta right now and is going free to play, so there's nothing to lose, besides time

Your characters from the open beta will also stay for the full version, as the final character wipe's already done.
