Like how agility will afftect AP and how strength will affect carry weigh

in GECK go to Gameplay -> Settings and look for:
fAVDActionPointsBase - it's set at 65, so your starting Action Points are 65.
fAVDActionPointsMult - it's set at 3, so you get 3 Action Points per every point of Agility.
fAVDCarryWeightsBase - it's set at 150, so your starting Carry Weight is 150.
fAVDCarryWeightMult - it's set at 10, so you get 10 Carry Weight per every point of Strength.

Awesome, learn something new every day XD
