Even 1% in any of them should allow colonization of that type, even if they didn't get much use from the planets.
Hold it, am i reading the above correctly?
I always assumed the pattern of Extreme-Colonization was a two step affair. Ability+1 means 50% upward capacity until last level has been reached for full access.
The reason i'm asking is that my mod could also use a bit of fiddling with these values & properties.. since, in the already listed new techs i have some *yet to implement* factors about all harsh planets and even down to the surface tiles level (which would only need more *enhance* levels beside the 123_YOR default schema).
What i'd require is a sort of break-out linear growth on the abilities with something like; from AQUA_ADV_FINAL (0,50,50 = 100%) to AQUA_ADV_ULTIMATE_FINAL (0,25,25,50 = 100%).
You could also read the last post in 'About the Custom planets...' (In Moddings) thread to learn how i perceived the entire theoretical concepts for new Colonization techs and necessary working tile enhancers.
Is any of that possible mod wise, Kryo?
