I've not played Nier, so I don't know about that.Doesn't it play similar to Nier? I think ER is an action JRPG. there is more emphasis on player skill but that's the only major difference. seems like you can still grind / cheese to become OP like in other JRPGs. You can't do that in zelda for example which is more action than rpg.it shares no combat mechanics with an actual JRPG.
also jrpg doesn't have to be party based, Ys series comes to mind. Also Dragon's Dogma might be similar tho I haven't played it.
Ys seems to be more commonly described as an ARPG with a JRPG story structure than anything else.
Elden Ring can be beaten at level 1 if you are good enough, so while grinding is an option it is not needed as player skill/knowledge can compensate.
Elden Ring does not have the traditional narrative-heavy, linear structure of a JRPG.
Dragon's Dogma has stronger RPG elements than Elden Ring, skills are character-based and gained by increasing vocation ranks rather than gear based, and you have a party.
I'd also suggest the Dragon's Dogma series are ARPGs more than traditional JRPGs.
