Me and my wife are making up a Dr. Who role-playing game for two players (alternating GMs), We did our first playtest yesterday. Needs work but the basics feel very promising. Very low-prep, you land in a place & time and "discover" (i.e. make up) what's happening there as you go.
If we publish it we'll just leave out all the copyrighted stuff and call it like "space/time travel buddies" or something.
@bankuei feels good to role-play again even a little bit, after years of not having time to!
