@profoundlynerdy@mastodon.technology #SavageWorlds is lighter than #DND, but not to the extend of #Fate.
#CortexRPG is a good framework with simple core mechanics. The framework is modular, so can be very light if you want. https://www.cortexrpg.com/compendium/explore-the-rules/
Look for fantasy games, or whatever genre you want, built with Cortex Prime.
Cortex can get quite crunchy with the dice pools, but remains inscrutable, which limits power gaming, e.g. is (3d8 + d12) better or worse than (2d6 + 2d10 + d4) ????
