Effect value divisors
An option so obvious that should have appeared alongside with multipliers: another effect option
divisor. To put it shortly,
if reqs then effect[type] += value * (multiplier // 1) / (divisor // 1)
Divisors shall be either nonzero shortint constants or names of corresponding game options and (not player-controlled) parameters. Goals are obvious:
1) Multipliers modify effects too rough without division;
2) Better ruleset scaling, most notable, Tech_Parasite can't be now set to a % of players (need divisors like "Live players", "Human players", "Normal players" and "All players").
