Royal Grail indeed!
The first one was one of my favourite games released this year. This doesn't look like TOO much of an 'upgrade' or 'change' though, so thats a minor disappointment, the least they could do is give the interface a minor color change, so that it feels a bit more fresh to the eye.
I'm hoping it has some form of multiplayer, it would really be all kinds of awesome to venture in these quests with a friend. Hastily drawing penii and vagii on the map.
