IMHO, nothing should auto-repeat without there being an option to turn it off (and preferably have it off by default).
Agree with this. If Stardock choose to make something repeatable with one mouseclick, it should default as nonrepeatable until that mouseclick is made.
Maybe this could be a game setup option - making Missions, as you get them through Research, autorepeat or not. But how long do we want the game setup to take? There's plenty of options to think about as things stand...Do we really want things to get to the point where it takes twenty minutes to set up your next Galactic Civilizations III game?!
