I have the first one, we've nearly completed it. Big problem we've had is that we stopped playing it for a while part way through and then when we got back to it couldn't actually remember what we were doing!

Funny enough got the second for Xmas as well. Haven't played it yet though, want to complete the first one first.

The first one is good. I like the story, the game play gets a bit samey after a while and I've left a lot of the playing to David, but in short bursts its really quite fun. Hoping the second one is as good as people have said!
