Researching everything naturally happens in a long game. The current achievements go back to vanilla sins so they are mundane and or repetitive. The research achievements in particular WORK as achievement because if you only go for the military you lose out on colonizing Ice / Volcanic and are susceptible to culture attacks. If you chose the civilian side you lose all of your ship designs and titan. Unfortunately in both scenarios you can't use the defense or diplomacy techs either further gimping you. 

Really all that needs to be altered in those achievements is the addition of defense to the military and diplomacy to the civilian. Either way you can use allies to attack for you or fortifications to fend off attackers better.

That pretty much says everything about it.

I also tried the Vasari "pacifist" achievement yesterday, but i didn´t get it. (although i met the conditions)

Maybe it was because i played with research victory (which is also located in the civilian tree, but i also reached victory via this tech, so i should have got the achievement.

Seems bugged
