Where can I found file with pickable luxuries? I mean, I wanna modified gen. galaxy for all luxuries in the game. How can i did it? Or it's impossible?

In "Endless Space 2\Public\Settings\WorldSettingDefinitions.xml"

There is LuxuryResourceCommonTypes, LuxuryResourceUncommonTypes & LuxuryResourceRareTypes for each galaxy size, setting them to 8 should have all luxuries spawn

Wow, thank you, sir :D 

Very helpful answer! 

Yes, very helpful.  Thank you.

I keep finding luxury resource production slows down my game as I can't expand.  I've tried many different strategies and I always bottleneck there.  I'll play with those numbers and find a good balance between easy system development and choosing luxury resources that specifically help my empire.
