>>35359029Shin Megami Tensei doesn't have onilne but that doesn't mean it doesn't reward or hugely encourage strategy in its difficult superbosses since it has an actual good postgame unlike Pokemon and it still remains an actually good monster collecting RPG.
Monster Hunter games have online and hugely encourages strategizing and working together with teammates to go after the big and rare stuff.
Yo-Kai Watch 2 has the same deal as SMT. Actually deep postgame that rewards strategy plus it has online battling wtih an actually fair official banlist. Also a good monster collecting RPG that rewards a ton of strategy. The Busters titles have the same appeal as Monster Hunter: online strategizing and teamwork with others.
If you REALLY wanted an RPG with huge emphasis on online, there's a genre for that. It's called an MMO.
