People complain about it a lot, but I’ve never actually ran into a system that uses any maths beyond what a five-year-old should be capable of. Closest I think might be Mutants and Masterminds with stacking multipliers, but still just some extra steps. Nothing that knowing your times tables wouldn’t prepare you for.
I think more like “I play baseball” Vs “I play softball/rounders/cricket”.
It’s not that difficult to convince people who enjoy little league to try standard baseball.
