To use another IRL example, humans did drive the wooly mammoth to complete extinction with little more than sharpened rocks attached to sticks.
Humanity’s ability of cooperation is a massive force multiplier and let’s us accomplish tasks that would kill and individual.
I really like WoD’s Resources background, one thing I do tend to append to the rules is separate out recurring income from lump assets.
Basically Income Resources are used up and refresh each month worth of time provided players maintain their income or have retainers keep watch over the accounts. Lump Resources are like having a big pile of gold, or a big inheritance from an eccentric uncle or just a bunch of money in a savings account. Once they’re used up, they’re used up.
