Since we get a lot of posts providing suggestions for franchises that Telltale should tackle, it makes sense to keep them all in one place, lest the foru-COMMUNITY get clogged up with loads of these threads.
So if you have an idea for what Telltale should do next (BESIDES more Walking Dead), then please post it here rather than in its own thread, since we'll just move it here if you do and you might as well save us the hassle :p
First up, @the_herbalist made this suggestion (sorry about this - I can't move OPs into existing threads, just the subsequent responses to it):
I think if anyone could do the series justice, it would be TT. The problem I have found with the currently available games are that they are too focused on 'action' and not on the interactive adventure element.
Perhaps you could play as multiple incarnations of the Doctor as the story progresses... or have a multi-Doctor story as the main idea? Something that could have worked well or the 50th Anniversary this year.
