You should not tax PCs by this method if your game is:
- Adventure Focused / Heroic (Lord of the Rings, Dungeons and Dragons 5th Edition)
- Character Focused (driven by the interactions between players rather between players and the world. Drama-based.)
- Not Medieval (there's less incentive to use this in an Early Modern setting, Cyberpunk futures, etc. You could potentially adapt it for post-apocalyptic games though.)
- Beer and Pretzels (light, fluffy fun with low commitment)
But if you'd like to run a more detailed semi-medieval game without adding dozens of subsystems and extra rules, read on to see why I'm suggesting the ludicrous things in the previous post.
