I thought about doing this in my initial proposal. Held off because the thought was that if you don’t spend your money to help you win that is your fault. But I really have no strong preferences either way.

If players don’t spend all of their money and yet still get to the victory tiebreaker, how much they didn’t have to spend seems worth recognising.

I think plugging “how good were you at gaining other resources?” tiebreakers in is always fine for finding out who the game thinks the best player was, before we give up and toss a “we literally cannot tell who played better here” coin.
