As I said in my review, a game based on this era would feel very different to one based on Nu-Who. That's not just because of the 50-year gap between then and now, but because that era told, on the whole, a quite different kind of story. In a way that, for example, Troughton's era didn't. So I'm not actually planning on running a campaign set there, interesting though it might be. A one-off game, though... yeah, that's a possibility. For a con, maybe. We'll see.
Still, one of the things that strikes me, re-watching these old episodes, is how much like a role-playing game they do feel. More so than the new shows, in fact. I think a lot of this has to do with the pacing. In more modern TV shows, a lot gets elided that doesn't if you're playing it out. That a lot this was kept in in the 1960s style of show does sometimes make it easier to view things through an RPG lens.
For instance, there's a scene in 'The Dead Planet' (that is, The Daleks #1) where our heroes come across a mysterious box, and cautiously prod it with a stick from a distance a few times before convincing themselves it won't go boom. This is the sort of thing that PCs do, but one expects Matt Smith would, at best, wave his sonic screwdriver over it for half a second, and probably wouldn't even do that. Heck, that entire episode basically consists of the characters wandering around trying to figure out where they are, something that PCs tend to do a fair bit of, but that would be rather out of place in a single 45-minute TV episode.
