So I think I enjoy fucked up balancing in RPGs, and most of them are TOO balanced. Can you guys recommend me some JRPGs that are actually poorly balanced? Too hard or too easy, but nothing in between.
That's a tough one. Most JRPGs are technically pretty unbalanced if you're nitpicky enough, but the mild difficulty generally papers over it.
There's quite a few NES RPGs that are a bit difficult early on, get a lot easier through the mid-game as you and your team are more prepared to handle things, and then suddenly it starts raping you in the final dungeon because developers didn't have time to fully playtest it. The first Mother (EarthBound Beginnings) and Dragon Quest II for instance. The first three Final Fantasy on NES have shades of it.
There's not too many games people will talk about often that are really hard early on and then get easier, since people will usually get frustrated and stop playing before then. Earthbound kind of just avoids that through sheer strength of its charm. Closest thing I can think of is Fire Emblem: Radiant Dawn, where the first fourth-ish of the game is the hardest part because you're given a lot of mediocre to shit units, and then it gets easier as it goes on because you get more and more strong and busted units, but that's a strategy game so probably not what you're looking for.
Just some spitballed ideas for reccomendations
Live-A-Live - Weird, experimental RPG where you play through different unconnected storylines with different protagonists, each with their own gimmick in the gameplay or structure. The battle system feels like it wasn't thought through that much, so fights do tend to be either cakewalks or frustrating. Though overall, it does tend towards being easy.
Treasures of the Rudra - This is a weird one. A lot of the battle system revolves are your spells. which you actually "make" yourself by entering a spell name and the game procedurally generates the effect of the spell based off the name. The game's difficulty depends a lot on what spells you generate, with the inherent quirk that you make the early-game way easier by already knowing good spell names. Even if you look up the best names on the internet that generate spells with powerful effects and low MP costs, the final stretch of the game is pretty brutal and I remember the final boss taking forever to kill.
The SaGa series in general - This entire series is known for being weird and experimental, and that tends to lead to some weird balancing. I've yet only played the first two games on GameBoy myself, but I found the difficulty curve in the 2nd one pretty weird, with a slightly tough early-game, mildly easy mid-game, and suddenly tough to the point of getting annoying endgame. The balance between races (basically classes) is really wack too and will have a big effect on diffuclty. While I haven't really spent time with later games, the first SNES one Romancing SaGa is a full-on open world game where difficulty can fluxuate a lot based on your team, actions, and how well you know the game, and a really tough final boss. And I've heard people say each of the Romancing SaGa's final bosses are nearly impossible without optimizing your team beforehand.
Phantasy Star II - I wouldn't even say this is a good game. People are only fond of it because it has a somewhat interesting plot and there was no other RPGs on the Genesis when it came out. The dungeons are gruelingly tedious, the combat is really simple, and you have to grind forever in the first half of the game. It certainly is really unbalanced though. The early game will rape you until you grind for multiple hours, the rest of the game is mostly braindead easy except for like one really tough boss about halfway through, and then the final boss at the end is quite possibly
the most
bullshit final boss in the entire genre.
