And with the actual writers from the show. The existing
adventure game series benefited from that. In fact, it's practically the only selling point to the games, other then the fact they're not awful.
Telltale, take note of the amount of interest this game would generate. This guy used up his first (and as of posting, only) post to say how much he'd like a game. And on that note, welcome.
But yeah, it would be fantastic if you guys would make such a game. You're the best people for it. Unfortunately, as the BBC have already given the license to a company making a series of adventure games, it's unlikely. Plus, the BBC would probably like them to be free to UK tax payers, which TTG's head honcho's wouldn't be too pleased with, i'd imagine. And I think organising the voice talent would be a nightmare, with Matt, Karen and arthur busy filming doctor who in the UK for 9 months of the year.
*edit* @shauntron Now watch as your comments get blown widely out of proportions in a similair fashion to the wii-toaster comment...
