I miss Tony too even through I like what they did with the TV show and agreeing with the rest. :) looking forward to what you come up with, when you decide to come up with it. :)

did you ever hear of Dreamfall or LongestJourney? (they are a pair of adventure games)

be careful through, they are dangerously addictive.

I don't know but me thinks especially Dreamfall could give you some material to work with (crossover or single fandom)
