Xenosaga, Shin Megami Tensei, Valkyrie Profile, Grandia, Breath of Fire, Shadow Hearts, Radiant Historia... I mean what is an "obscure" J RPG at this point. Every J RPG seems to be "obscure" since it's a niche genre. But really those are.... "classics" for me. (With maybe the exception of Radiant Historia since it's more recent but i see it quoted everytime someone talk about DS's library and especially RPG as THE best J RPG of the console, not exactly a hidden gem, even Contact would fit the bill better and i'm sure it's not really obscure).... Nah, the reality is i don't know what game could qualified as "obscure" either.
Like the one i could talk about is Mother 3 because he never came out of Japan but with Lucas in Smash, it may not be as obscure as we think.... But this is one of the best J RPG i have ever played, without a doubt !
I could talk about Rudora No Hihou which i deeply liked at the time (one of my first J RPG mind you), but with a lot of twist and the idea of those 3 scenario which interact with each other is really cool), but like all J RPG in SNES, it's very likely that anyone knowing the SNES library knows about this game.... But people prefer to talk about other RPGs... (But i'm actually very happy stuff like Terranigma seems to have the success it deserves)
Maybe we can talk about Baroque on Wii/PS2 ? I feel like everyone knew about this game at some point but now, i don't see any mention about it anymore. It's a very interesting D-RPG with a very neat atmosphere. The remake was translated in English but not the original version which was even creepier unfortunatly.
What else... Someone talked about Metal Saga, it's actually the follow up of the Metal Max series, i only played the "Metal Max Returns" version on SNES since it was translated and it's quite original since you don't really have a "aim" other that killing all those wanted people.
I could talk about Legend of Heroes V : Song of the Ocean, because it was really badly written in English with a very uninteresting remake on PSP, the whole Garghav Trilogy don't appear pretty to our eyes. But i feel like it's the best one out of the three even with all those problems, the engine run better, the characters are more interesting and the way it connect the story of LOH3 and LOH4 is really neat. I think a lot of people "know" it exists but i don't think many played it. (Since you will have to play the 3 and 4 before... And i actually think the third one is really boring but i liked the fourth)
There is a lot of other stuff, what about Mystic Ark in SNES which is a blend between J RPG and point & click adventure ? It has a mystical feel to it... It was a chore to translate too !
I could talk about Live A Live with the fact you can chose 7 different scenario made by totally different people before unlocking the last one... It's very original and a deeply engaging experience for me but surely, everyone know about that game, right ?
I don't even know anymore what is an obscure RPG or not... The other day someone told me Suikoden was obscure... Come on, Suikoden is a huge classic right ?
