A Doctor Who game should be a point and click puzzle solving type RPG... like Day of the Tentacle. Also, multiple Doctors. What other way could we have Tom Baker return to the role?
I once got into adebate with someone who referred to Boba Fett as an inter-galactic bounty hunter. I don't ever recall a reference to more than one galaxy in Star Wars...
Why limit yourself? With the two properties involved I think the most likely medium to make this happen would be comic books. So why not a series where a different incarnation of The Doctor arrives on a different version of the Enterprise - say, Patrick Troughton on the TOS Enterprise, Tom Baker on the '80s films Enterprise, Sylvester McCoy on TNG circa season 1-2, David Tennant on the TNG films' Enterprise, Matt Smith on DS9, Eccleston on the NX Enterprise. Something like that could be EPIC.
Agreed... somewhat. But I think it wasn't so much 'being a warrior' that River was calling him out on, but more that he was starting to believe his own hype. In 2005, Nine had a computer virus that erased all record of his existence from the computers of earth. Towards the end of Ten's run and into Eleven's, we're seeing a Doctor that is much quicker to embrace his own image. How many times has he given an "I'm the Doctor, pretty much the baddest SOB that ever walked the cosmos. Run away!". Moffat touched on this in an interview I think posted on this very site today.
I always thought it was odd that Tim Burton cast Keaton as Batman when his Beetlejuice was practically the Joker. Especially given how Alec Baldwin (also in Beetlejuice) basically is Bruce Wayne.
They could explain the aging by having Jack periodically go on some sort of a time travel adventure between seasons, and be very vague about how long he was gone from his own perspective.
@FartyMcPooPants: I'm not sure the show has the FX chops to really pull it off... unless the previous incarnations appeared as TARDIS holograms that have made a few appearances in recent seasons. That way you could camouflage dodgy CGI.
