Now I shall continue talking about how fantasy role playing is unrealistic.
Another reason that fantasy role playing is unrealistic is unarmed attack damage. Yes, people don't usually do a massive amount of damage when you attack with fists or legs. And I am not saying that Role Playing Games should have that kind of damage there for unarmed strikes. In fact, I think that is bad, but I do think that unarmed strikes should do an amount of damage that is in the middle of a common dagger, and the damage they use for unarmed strikes in D&D 5E (1 Hit Point of Damage).
Having damage be in the middle of those two damages is just an average of what I think a damage from a fist or kick should be.
Now lets dive deeper into this.
When you wrestle the damage you do to your opponent is largely based on your strength, not anything else. In games, however, there needs to be some ruling to this, so, lets say we use a table that does damage based on your strength. Below is the table:
Weak Strength: You deal 1 Damage
Medium Strength: You deal 3 Damage
Strong Strength: You deal 5 Damage
(If you wrestle with someone you deal 2 extra damage)
I think that this is good idea, and you can import it into your game however you like, because I tried to make it system free as possible!
