Not much to offer for the hardcore players.
The graphics are medium quality, allowing older slower systems to run the game. However, it lacks support for the few month old Windows Vista. It's frequently releasing patches containing content updates, which is a good thing; everyone likes new content. However, when stuff breaks - they find it hard to get unbroken.
Recently their cheat protection software banned a few players due to an error, it thought Windows Vista was a hack/exploit. Very furious these players were, but the GMs acted promptly and resolved the issue.
It doesn't have an all attractive soundtrack either. My suggestion is to turn down the volume of the music, and turn on your own.
Playing with your friends can be fun, but after a while it gets old.
