This pretty much speaks for itself.
Name any obscure/underrated games that you know of here.

[Sable-Xeno]

Whoo, my kind of topic. :U Lesse...Klonoa isn't quite obscure anymore, so what else...

Mischief Makers
Elebits
Solatorobo
Chameleon Twist
Psychonauts
Tonic Truoble
Graffiti Kingdom
Chocobo's Dungeon 2
No One Can Stop Mr. Domino
Vib Ribbon
Kororimpa: Marble Madness (and its sequel, Marble Saga)

Just to name a few.

^{(I think we had a topic like this before, but oh well...)}
Klonoa is already a given, considering this forum is entirely based on the series. But there's a lot of other obscure games that I like, those being:

Rival Schools: United by Fate
The Misadventures of Tron Bonne
Garou: Mark of the Wolves
Tatsunoko vs Capcom
Demon's Crest
Summon Night Swordcraft Story 1 & 2
Rocket Knight Adventures & Sparkster
Lethal League
Vanguard Princess
Freedom Planet
Jet Force Gemini
Hybrid Heaven
Turok series

There are more, but these are all I can name off the top of my head for now.

Okage: Shadow King
Okage: Shadow King
Okage: Shadow King

Digimon World
Monster Rancher

[Meguumin]

I know a few:
Chibi-Robo (the Gamecube one, rest kinda suck)
Captain Rainbow
Moon RPG Remix
Contact
Wario Land 4
Majora's Mask
Okami (not overly obscure but very different from most and is extremely good)
Super Monkey Ball 1 & 2
Vampire Savior (unusual Crapcom quarter-eater fighter, can be hella broken if it gets intense enough)

The first three were developed by the same dude, I forget his name though. He's well known for creating really unique games with odd art styles and Moon is his most successful in Japan. I'd say Chibi is a close second since both have very similar themes. Captain Rainbow is much like those two but it's... sorta weird and raunchy compared to his past works.

Contact is one I haven't really explored enough but it has a cool and almost unexplored setup :U

Ok then, let's do this.

Here's mine:

-Metal Slug
-Project Justice
-Legend of Mana
-Chocobo Racing
-Legend of Legaia
-Tactics Ogre
-Advance Wars
-Strider
-House of the Dead
-Harvest Moon
-Destrega
-Wolfenstein

And there's more where that came from.

That's all what comes to mind for now.

[Voka~Daemyn]

I don't see Tomba/Tombi on here.
That was an odd game in my childhood I should revisit again.

[Artsy]

I have to be honest, I have no concept of what games are obscure or not

But I really love Goof Troop for the SNES, me and my sister would play it all the time, and I couldn't find much about it online until the Game Grumps played it, so I guess...? It's obscure??
