madsoul got two of mine, Hitchhiker's Guide and the Discworld series. I presume you've played Discworld Noir madsoul? I know you like P&C games so it's a safe bet you've played it too, what a game.
havent played Noir yet but my brother did when it was new. But i have played the older Discworld games:
the first one is epic. love it.
Also, have you tried Starship Titanic? Starship Titanic - Wikipedia, the free encyclopedia
a game by Douglas Adams. I liked it alot when i played it back in the days.
