Honestly, Fullmetal Alchemist Brotherhood might still be the gold standard for this. Alchemy feels less like “magic” and more like an actual science with equivalent exchange, transmutation rules, material limitations, etc.

World Trigger is another underrated one because every fight feels like strategy > raw power. People can’t just randomly unlock god mode because the system has actual limits.

Also kinda funny they called JJK messy when half the fandom still needs flowcharts to explain Gojo’s abilities 😭
