Overleveling vs Underleveling

[Zero Kirby]

As for overleveling not dragging things out, yes, you do have to see the same random encounters (or the same screens if it's a real-time game like Secret of Mana) a bunch of times, BUT, it's not within the same fight, as I put in caps before. Think about how easy it is to grind for a while, put the game down, come back later, grind more and then continue, than it is to run from every battle, get to a boss fight, and have to do the same fight like 6 times until you finally win, probably by luck since the enemy didn't score a critical or whatever, or if it was by "skill" then all the resources you wasted on that single battle. And I don't mean "easy" difficulty wise here, but how it wears on your attention span.

Different people have different attention spans

I can tell you right now I find the occasional boss encounter far more interesting than grinding the same random encounters over and over again

I don't think grinding is fun (Kingdom Hearts is an exception because the combat in that game is fun), so whenever I come across a part where I need to grind, I tend to dislike it and am inclined to stop playing. Most people play games to have fun and some people think underlevelling is fun

You aren't going to convince people otherwise since you don't seem to understand why

Also when you say most battles underlevelling are won by luck just because the enemy didn't score a critical, keep in mind they can score criticals even when you're overlevelled and then wreck your shit, especially if they do it multiple times in a row, forcing you to "waste" resources you otherwise would not have used. So in a sense, you could say you're always winning by luck whenever the enemies don't score criticals. Even when you're overlevelled.
