The Shadow
Hero
Fine. S&V has an amount of Upkeep charged after each job. It goes up with better-quality ships, so as you improve your ship over time it gets more expensive. That Upkeep fee is taken out of the amount you earned on the job, and it is painful! If the job didn't pay enough (or your employer stiffed you...) you can be in a world of hurt.I just wish you could have given an example. To say some game I've never heard of has a great system does not help.
It's possible to skip upkeep, but then you have to make rolls to see what goes wrong, and those can also be quite painful. If you're lucky, you can make it through a few skipped upkeeps. If you're not... Very bad things can happen.
None of that involved tracking X amount of air, Y amount of water, Z amount of parts. It's all abstracted.
You're familiar with the abstraction that is hit points, right? It isn't necessary to track the location and severity of every single scratch your character gets.You keep track of things or you don't: there is no middle ground that I see. The Archer has 20 arrows or infinite arrows. If you would say they have an impossibly high number of arrows like 500, then sure that is "less" then infinity, but it's still the same. If you say the archer automatically gets 20 arrows at the start of any encounter, again that is still infinite.
In a similar way, you might have "supply points" that get depleted, but don't involve tracking every single thing you're carrying, or every single thing your ship might be lacking.
Ironsworn does something similar to this, with the added twist that your Supply is an actual (deplete-able) stat that you can roll against.
