Or even houserule to replace it with something else.

Top Secret 1st editions only melee combat rules are an elaborate double blind mess for anything but climactic duels.

WWN and it’s factions system. Didn’t really get the point of it. Love the game though.

Other than encumbrance?

Shadowrun decking AND rigging

I do not use Might in Legend in the Mist. I handle scale the, perhaps old-school, PbtA way of having more checks to accomplish the goal. I don't give you a -3 because you are attacking the dragon, I make you roll to get close enough to attack the dragon without it biting you in half and then have you roll to attack. I feel it flows better from the fiction, and is more interesting than a simple modifier to the roll.

Pretty much every sci-fi game I own or have played and their starship combat systems. Nothing has ever been good, although I'm holding out hope for GURPS Spaceships (if I ever run it).

The full hacking rules in Eclipse Phase are a lot.

Prey ( 2017 ) has mechanics that penalizes You for taking alien Powers. The powers are so insanely fun that i don't care

Every game and their skill system.

I made my own that is flexible and simple and just use that unless I'm trying a new system for the first time.

I'm curious, what is your skill system?

A good chunk of Burning Wheel.

i really like how Star Trek Adventures does it, the key is that you can use each other's stations at a penalty

My man this videogame isn't even an RPG how did we get here

This one is specific for a BECMI game I'm playing where we can't keep a thief in the party (they had to change days and is now in a different game I run).

It's based off old D&D mechanics funny enough.
