Our view points on HP differ greatly.
HP in OL could be described as “plot armor” although however, many posts in the community by now have pointed out how HP really isn’t HP.
It’s actually more accurately to be described as Stamina instead which I agree with.
The reason why you can recover back to full HP after 10 minutes after a bloody fight isn’t because you just suddenly recover all of your wounds within those 10 minutes, no!
Your eye is still missing, your bones still broken, and your open wounds, still very much open.
Your HP fully recovering represents you’ve finally recovered from the adrenaline rush of a combat, you’ve calmed down and now you are prepared to take on the next challenge. But those wounds still remain, and they definitely will still bother that character.
It’s why you can invoke the Heal boon with Presence by giving a rousing speech.
A rousing speech does not close wounds, but it does arouse the heart.
In OL I don’t just specifically use HP for physical injury, punching, stabbing, shooting combats, I’ve used them on conflicts where not even a single punch was thrown.
One combat scenario forced the party to play an intense poker match, another time they had to play a high stakes game of freaking tag!!! … Tag!!! And HP in those scenarios weren’t simply used to display typical injuries like cuts and bruises, but rather it was used to represent how much stress they could still handle, their energy to still continue running and chasing, and continue making rational bets, calls, and folds. And even someday along the line, a rap battle.
In that sense, HP isn’t plot armor, but rather a lose condition instead. A vague representation of your closeness to losing.
But that might just be me.
I can’t really criticize you for making a rule due to a reason like this as I too do this.
Even today I still create house rules to implement mechanics from other systems into the system we are playing. It comes from my innate desire to play every system at once. Though I wonder if that’s just me who feels like that.
Also I too don’t know what the heck Expanse is. (yet)
When I began, along with a proposal to doing HP differently, I also devised an “intricate” (translation: Poorly written) spell casting system because I really wanted D&D in my OL.
This was years before good 'ol VanGo created a homebrew spell casting system for OL that is literally just better than what I wrote in every way possible.
And later on when I got introduced to Call of Cthulu I immediately wanted to try implementing the luck mechanic in that game to OL and other systems because of how awesome I thought it was. They kinda sucked though so I never posted them to the community.
It’s fine to use other systems rules for inspiration for creating homebrew or even outright your own TTRPG ruleset, and even better when you use them to replicate something I believe. And the more you do it, the more you take, the better you become.
I assume that means it has no bookmarks for the pdf either? That kinda sucks.
