Name the most obscure game you know

[Beed28]

Holy Diver, a heavy metal inspired fantasy platformer which never left Japan.

Also, it's nearly impossible. The one guide there even states that it's harder than Battletoads (!!).

[Kapus]

The Wonder Project J duology, Magical Pop'n, and Miracle Girls. All of them are on the SNES, with the exception of the second Wonder Project game, which was on N64. All of them are Japan only as well.

They're all super neat and fun to play. Well, except for Miracle Girls.

[Medley]

Isn't your current avatar from Miracle Girls?

[Knux]

I saw the title screen for that game a few years ago, so I'm willing to bet it is.

As for an obscure game, Vortex (SNES). Huge levels, elaborate music, but kinda short.

[Tfp BreakDown]

CyClones
Eradicator
Corridor 7
Rise of the Triad (1995 version)
Marathon Trilogy
In Pursuit of Greed
Witchaven
Strife
Blood
Shadow Warrior

A couple of not very talked about FPS games, So far only played Marathon 1, pretty fun, challenging, and punishing. Haven't tried the others but I do want to try out the first four mentioned (As well as Blood, Strife, and Marathon 2: Durandal, Marathon Infinity)

[Galactan]

Ribbit King???
Frogger's Adventures???
Every time I mention those in my area nobody has a clue what I'm talking about.

The most obscure ones I can think of at the moment are "Werewolf Simulator" and "Skull," both of which are for the ZX Spectrum. The former is something of an old-school adventure game, which primarily involves you solving a series of murder mysteries that may or may not be linked to a werewolf. It is sadly, not about controlling said werewolf and ravaging towns in the middle of the night...you know, the very thing the title of the game practically implies.

Skull, on the other hand, is a rather interesting game. Why, exactly?

Because it stars Jitterskull's long lost brother, that's why.

[Mr.Faq2014]

The Witch's House for PC (It's not that unknown but it isn't also too much the number of people who played it)

[Azure Sky]

Shienryu for Sega Saturn

[Biotronius]

Another obscure game I know is the Dreamcast version of Mobile Suit Gundam: Federation vs. Zeon. Practically no one knew there was a Dreamcast port. That, and it's a Japan-only release.

[Turbodude]

This piece of shit, right here. I don't think prototypes really count, though..

[Biotronius]

That looks vaguely similar to The Ooze which is another obscure game!

[Turbodude]

At least The Ooze was actually fun.

Also, Strife is pretty obscure despite being pretty revolutionary for the FPS-RPG genre.

[Jdude330]

Super Mario 128: an obscure techdemo of 128 Mario's running around while you control both them and the ground. it was later split into 2 projects: Mario galaxy and pikmin.

Rockman EXE Operate Shooting Star: Magaman.exe X Megaman Starforce. it plays in Battle Network style, but each character has their own abilities.

[arkman]

Dwarf Fortress and Cataclysm DDA, there is always somebody who hasn't yet heard of these low budget leviathans

Magic and Mayhem, one my favorite games, its a kind of strategy/puzzle/rpg
