Good topic to discuss, Oleg
Technically, the XiChung does not research Gas Giant Colonization accept if you are Playing a No Warp Game or the XiChung is currently disconnected in your game, I assume both are not the case.
It is also probable the XiChung was awarded Gas Giant Colonization thru an Anciant Ruin; in your current "game turn 60" game
=========
Please Note ... in AIC, the AI has the Ability to acquire other type Colonization with out research, as Human Players do, thru Trade offer.
As many Players should agree, as a Human Player. Receiving a Colonizer Tech from most, if not ANY AI Players is so, too simple. Agreed?
Since AIC�s initial release, I have had the AI Player programmed in AI Campaign, also to receive their Colonizer techs as well, in an ambiguous (TRADED) fashion. With AIC the AI Player will receive a free Colonizer tech and all at a point of time in your standard warp game, for each specific planet type Race.
For example:
The Gas Races will receive 2nd ability to colonize a Rock Type Planets, in about the first 25-30% of their evolution.
The Ice Races will receive 2nd ability to colonize a Rock Type Planets, in about the first 30-40% of their evolution.
The Rock Race will receive 2nd ability to colonize Ice Type Planets, in about the first 40 to 45% of their evolution.
All Races will have the 3rd and Final Colonizer type about 50 to 65 % of their evolution process.
Please note: The more AI Bonus you give, the faster the AI will evolve
In a No Warp game, most
AI have to research at least one Colonizer Type , this may change to (ALL) in No Warp games in the final AIC release
