Very interesting thread
IMO SE4 doesn't need Platinum or Titanium Edition

, but a SCENARIO EDITOR would be most welcome...
What's lacking from SE4 is the ability to play with more consistent SciFi backgrounds, uneven settings (Star Wars type)or just situations outside of the "star race" standard.
Currently noone has done any satisfactory scenario AFAIK, and that's a pity because all other modding tools are here !
Basically if we could just setup "at start" techs, colonies, facilities and ships/units ...
