This game is so close to being the spiritual successor to MOO2 it's not even funny...
However there are notable exceptions, and probably the largest of these is several tech trees that seem to me to be truncated - i.e. they only have a few techs, and they end. Probably the most significant of these is the planetary "terraforming" tree - only a handful of techs and then nothing. I can accept the techs that may or may not allow you to improve marginal lands on your planets, but there is nothing (that I am aware of) that allows you to colonize and improve planets that start out being class "0". It almost feels like the game is a snapshot of the middle of a classic MOO2 game, without the cool planetary expansion and end game. The fact that you start the game with almost unlimited range and that the planets that are colonizable at the start are the ones you are stuck with for the entire game really limits much of the cool factor of exploration and expansion. Am I missing something? Why even have non-colonizable planets in the game at all?
Is there some way to mod this? i.e. add the appropriate tech trees and allow planets to be "upgraded" from class "0" to some other class, and to add other terrain types (i.e. lava, methane, etc)?
