How about this...
How many of you know about the
Tengai Makyou series? They exactly play like the Mother series (minus the Itoi writing, sure, but the wackiness, the humour and the sheer number of new ideas make up for it) but none of them were released outside Japan.
They are mostly set in a Japanese setting though, but
Tengai Makyou IV is set in the (fictional) US, and is hilarious all around.
A terrible pop singer that makes the youth of Seattle turn into werewolves during Satanic rituals, that in turn maul an Indian tribe chief when he does his "I'm a friend to all living things, for example this doggy..." speech... to coerce him to abandon his village so that she can build a giant cat-girl themed dome city where corrupt values thrive. And she's dressed like a stripper, and thus accordingly offers her body to the hero (who's a demon hunter who hunts demons in America) when they meet
A cannibalistic pig woman that promotes obesity as a sign of manhood, and incidentally collects flesh for the Dark Cult (she and Candy -the stripper singer, actually they're named the Apostles of the Dark Cult, and yes, they HAVE a church where said stripper's photograph are hanged with a homosexual crook mechant (who has a secret identity- leads the rituals) - they both do fully voiced musicals before the mid-boss battle). She attacks with her belly for massive damage.
An immortal monkey that proclaimed himself the ruler of Lake Tahoe (renaming it Lake Aho aka Stupid)
A film producer that kills actors casually and aspires you inside movies to battle their tormented souls before imprisoning you in Alcatraz and then challenging to a duel you and your Geisha Mecha Robo against the aforementioned immortal monkey
A book that turns everyone who reds it blue (even the NPCs) and to remedy this you have to create a party member: you draw him, you name him (and he reads his name aloud! 7 years before Tetra Trackers and 17 before Tomodachi Life) and then you enter the book that's a dungeon exactly like Paper Mario only better aesthetically
NPCs and battles are fully animated anime that take up the whole screen, battles depend on the timing of your key press (in the PSP version at least)
There's much more, but I don't want to spoil it
The plot is ridiculous, especially how you find out your soon-to-be party members are Chosen Heroes of Fire, and where the marks of the heroes are on their body
And any sense of political correctness is thrown out of the window.. besides the above, there's a black man who joins your party who has chains dangling from his arms for whatever reason. Oh, and he's the Jamaican coach for the (now zombified thanks to the Dark Cult) Mexican bobsleigh team.
Made by the same people behind the Sakura Taisen series.
PLAY IT. Learn Japanese for it, or use a walkthrough. The PSP version is the best one, even though it's missing some frames on bosses and finisher animations and some 3D animations (it's a mostly 2D game, doesn't matter.
Tengai Makyou Zero is one of the best games on the Super Famicom and is worth it, even though it's less humorous.
Manjimaru is a classic but you'll really need good knowledge of Japanese (it has a DS port), and its spin-off doesn't disappoint; but they haven't aged that well graphically. If you can bear FF4/5 spirites though, give those two a go.
