In the 
player setup-screen theres a button called "Civ-specific abilities". Now I understand that you can turn off the 
Civ-specific abilities table and civ-specific units.
But what if I want to play 
without that specific abilities table, but 
with the civ-specific units, or vice-versa? Not possible, I guess. 
Also, In the 
player setup-screen hope you add a civ-abilities customize button, leading to a 
editable civ-abilities table-screen. 
If I want to play a western Civ with a scientific advantage, I dont want to be force-guided to play the Russians. Russia was/is scientifically and technologically backward most of the time. Just give us a player-setup button that let us edit those 
civ-specific X-values manually (within rules/limits) for each Civ, with a back-to-default button also, of course.
