Maybe you knew, and I feel like a terrible Whovian for not quite keying into this one, but we're getting a new Doctor Who videogame in March! (By we, I mean this looks like it will be comfortably available in the US, on PC, PS3 and the new PSVita.) It's going to be downloadable, else I'd have the link for you to buy. If we get a chance to include that, we will.
Take a look at the trailer -- we definitely have Matt Smith voicing the Doctor, and I'll assume that's Alex Kingston as River Song -- plus several classic baddies to freak out my son. Thank you, BBC and Supermassive Games...
