I remember I played the demo for it A LOT becuase the levels were huge. I have played the whole game, though I can't remember anything about it all. I assume you mean the original?
My housemate has the sequel for the Xbox, though I've never played it, I don;t have any patience with video games, it needs to be fast and immersive. Playing poker uses up all my patience reserves.
And I'm completely obsessed ith backgammon at the moment.
