I played the first one until Wincewind ended up on top of a tower and the dragon kept flying past and I couldn't get down...So I gave up...
I played the second game and finished it, there's a great deal of trial and error involved if you don't want to use a guide, but it's great fun exploring the various possibilities, Eric Idle ad-libbed a lot in this game...
I got it from a friend last night so I'm going to go through it again, and I got DW Noir too, I have no idea what that one's like...Anyone?
