I’ve found that I like the traditional RPG format of base statistics, like
- strength
- dexterity
- constitution
- etc.
some important skills in particular are dexterity and willpower, or whatever you call your mental fortitude. in one of my favorite RPGs, dexterity played a role in many physical skills, as it’s a measure of your physical coordination, essentially. and willpower played into spellcasting, as your power to bring forth your magical energies. HP, stamina, and more basic attack and defense skills are alright, but I’ve found you can make a much more engaging system with the traditional RPG statistics like you’d see in DnD, being modified by other specific skills, racial or class bonuses, equipment bonuses, and so on.
