Actually looking into the
startscript documentation, using handicap would be a bad idea.
Handicap=0; // DEPRECATED, see Advantage (below). Advantage as percentage, common: [-100, 100], valid: [-100, FLOAT_MAX]
Advantage=0; // Advantage factor (meta value). Currently only affects IncomeMultiplier (below), common: [-1.0, 1.0], valid: [-1.0, FLOAT_MAX]
IncomeMultiplier=1; // multiplication factor for collected resources, common: [0.0, 2.0], valid: [0.0, FLOAT_MAX]
It's probably best to use IncomeMultiplier directly, as this is what we want to do.
