I think it would be cool if Telltale Games did an episodic version of Sierra's Space Quest series.
The Space Quest series was very fun, and (especially in Space Quest 4, 5 & 6, the point-and-click ones) had a very similar sense of humour to the old Lucasarts games. Space Quest 7 was cancelled after lots of work had been put into it, much like Sam & Max Freelance Police. It would be a dream come true for me if Telltale Games picked it up. Especially since they did such a good job at an episodic Monkey Island series.
I know that the fact that is Sierra, not Lucasarts, means this could probably never happen. However I think it would fit in well!
