world template system:like ME
For years ME has been giving SE its Hand-me-downs, with one exception..
They are amazing, having all my mods, all my world settings, everything, all neatly saved and waiting for me when I want to start a game. This would add so much to the game and end the problem of Keen trying to create the "perfect" starting template (which always seems to have something you need disabled). Instead let the players chose what they want for a world.
