Use powers of 2 and make it reasonably granular and you won't have 200 traits... nobody needs zillion +10/20/30/40/50/60/70 to mining traits when you can have just +10%, +20%, and +40%, and with those you can make any combination up to +70% with a granularity of 10%. And if you want to allow negative traits, you don't need +10, +20, +40, -10, -20, -40: you can just have -80, +10, +20, +40, giving you a range of -80 to +70. I know those traits need to be repeated for each thing (mining, farming, research, morale, etc.) that you want, but I'm just offering suggestions on how to optimize things!
