Two things 1) I haven't migrated to DA yet, I'm running DL 1.5 and 2) It's not just limited techs, It's ONE stinkin' tech per turn. Tried one out yesterday as Terrans (to get race medal) Selected max tech race pick, technologist party, spending slider to 100%, research to 100%. Got a home world w/ a precursor library. Suicidal Gigantic
Turn 1: rush built lab on precursor, researched Xeno Res
Turn 2: rush buy 2nd lab, research Adv Computing (did not get Basic Mini)
Turn 3: rush buy tech capital, research new propulsion
After buying the tech cap I had 424 research iirc. I learned new prop the next turn, and that's it...1 tech. Nor was there any "tech overrun" into Ion drive...just exactly one tech.
When I play a 'normal' game I don't get alot of research done initially. If I can get a tech in one turn I'm happy. But later when I'm rolling I can go back to something that I initially skipped, say armor, and rip through most of the chain in one turn. A riddle inside a mystery wrapped in an enigma
