I thought of something based on the Rogue Trader: allocating points.
All characteristics starts with 20 points and players have 100 points to spend on them, no more than 20 in each.
Then he adds the following modifiers according to their homeworld:
- Feral World: +5 Strength; +5 Toughness; -5 Willpower and -5 Fellowship
- Hive World: -5 Toughness and +5 Fellowship
- Void Born: -5 Strength and +5 Willpower
- Imperial World: no modifications
- Forge World: -5 Weapon Skill and +5 Intelligence
- Mind Cleansed: +5 Willpower and -5 Fellowship
- Noble Born: -5 Willpower and +5 Fellowship
- Scholar Progenitum: No modifications
I hope it is useful.
