I'm actually working on including a size system in the Steamroller™ setting, starting with STR. This is the crux and may be the only thing really needed other than unique equipment. I'm still adding the rules rule-by-rule and analyzing the needs of the setting and haven't come across anything else needing adjustment that I recall.

Abilities - Roll 5D for DEX, LOG, and WILL and add 30. STR has a special roll and bonus according to size.

> STR (Strength): lift, punch, swing, resist damage and poisons, etc. Use the Size table to determine the STR roll and bonus of races of various sizes.

Size (Full Length) Roll Bonus
Tiny (Less than 1'5”) 2D +10
Small (1'5”-3'5”) 3D +20
Diminutive (3'5”-4'11”) 4D +25
Medium (5'-6'11”) 5D +30
Large (7'-13'11”) 6D +40
Great (14'-27'11') 8D +50
Massive (28' or more) 10D +75

Also, I'm including a Gadget-like system that I'm thinking may include a scaling system for weapons and armor. I'll work on that and get back to you.

Pretty creative way of looking at the +30 score. Good job!

One could also simply take the attack modifier approach:

SIZE MODIFIERS
When performing action checks, characters get the following modifications based on their size:

Size (Full Length).......STR...DEX
.........................Mod...Res
Tiny (Less than 1'5”)....-30...+30
Small (1'5”-3'5”)........-20...+20
Diminutive (3'5”-4'11”)..-10...+10
Medium (5'-6'11”).........0.....0
Large (7'-13'11”)........+30...-10
Great (14'-27'11').......+35...-20
Massive (28' or more)....+100..-30

Characters get a +10 DEX bonus when attacking creatures of a larger size with a ranged weapon, or a -10 DEX penalty when attacking creatures of a smaller size with a ranged weapon.
