I'd like to see a whole season of parody based episodes.
Jurassic Park
The Terminator\Future War era (work well to bring back the C.O.P.S.)
The Davinci Code
James Bond
Akira\anime (good for 2D sections and super powers)
Lord Of The Rings
Star Trek\Star Wars
The Matrix series (good for slow mo and plenty of gunplay, and it's a nice extension of Reality 2.0

)
And for those Red Dwarf fans a take on Rimmerworld, only instead of a neurotic supercilious jerk we see a world populated by our favorite psychotic lagomorph.
Ialso like the Heaven and Hell idea. Maybe Max makes his way to Hell, sans Sam, and overthrows Satan. All of the other minions get tired of his leadership and Sam must team up with Belsebub to return his furry buddy to semi-sanity and the right side of the law.
I also like the idea of getting involved with the Dakotas conflict and I really really really want to see Max as a usuable item\tool\whatever you want to call it.
