Television Shows:

Spartacus (now completed and perfect)
Game of Thrones (probably needs another season)
Walking Dead (likewise, another season)
Dexter (ready now)
True Blood (ready now)
Doctor Who (four more doctors in and the show has never been more popular)

Movies:

Resident Evil (worthy of Stern's first LCD game)
Matrix (past its time, but I'd like it)
Ghost busters (see above)
Star Wars (make a good pin for this great series)

Other:

Updated wrestling game. Something like "Legends of Wrestling", bring back Hogan, HBK, Flair, Savage, Undertaker, Mankind, Stone Cold, the Rock, Andre the Giant, HHH, etc.

Anything with an ancient Roman theme or Greek theme.

I did forget about Futurama. That show would sell well as a game.

Another movie pin that would be a lot of fun is Highlander. Waaaaay past its prime . . . but it is being re-booted (sadly, it is being re-booted by Summit, the people that did Twilight, so I'm a bit frightened of the re-boot).

Oh please no . . . I would way rather see South Park re-made (actually, I think South Park should be given another shot as a pin theme).

Would be good. Outer Limits would be cool too.
