When I'm playing the game it feels like some of the stuff I enjoy especially with ground combat units unlocks a bit "too late" or cost a bit too much RP to be able to play around with in primitive or conventional starts until your already in the "mid game" or exploration phase. And for no real logical or good reason that I can think of at least.
For example stories where you just manage to get to space proper and find alien ruins on Mars you need to first put 5000rp into both Construction Equipment and Xenoarcheology Equipment before you can even design ground units to start exploring them.
Another thing I think feel odd is the boarding combat stuff (5000 RP for Boarding Combat Capability + 4000 RP for Troop Transport Bay + 6000 RP for Boarding Bays = 15k RP).
Not to mention the fighter weapons (3 x 5000RP) that have lots of potential for early game fun if they were balanced properly so they actually have a decent chance to hit ground forces / to damage, and so that AA is not super binary like nothing... nothing... nothing... all ground support fighters slaughtered.
Then we also have the Salvage Module (5000RP). Do I really need the same amount of research as developing jump drive theory in order to know how to dismantle an enemy faction space station I destroyed in orbit of Earth?
The only logical reason I can think of limiting these to later in the game is to not overload new players with too much information/stuff right away, but let's be honest here... Auroroa 4x was never designed to be friend to new players to begin with
