I'm looking to go back and revisit my PS2 to play games that. I'm looking for game that no one really knew about that were fairly fun.

Please, no big name games. I already know about it, I assure you, and it is not what I am looking for.

I'm looking for things like Echo Night and Disaster Report. Stuff that most people wouldn't give a second look and most reviewers would throw to the dogs but are actually pretty fun when you play them.

Amplitude: The Guitar Hero BEFORE Guitar Hero

Played that, and Frenquency. Nice suggestion though.

Urban Chaos: Riot Response

pitfall the lost expedition ! honestly one of my favorite games of all time!

I-Ninja and Kya: Dark Lineage. Both fun 3D platformers.

I will try:

Strategy: Romance of the three kingdoms 7-10, Kessen 1-3
Tactics: Disgaea 1 and 2, Dynasty tactics 1 and 2
RPG: Okage shadow king

All pretty low in name, but I personally found them fun.

I-ninja, Rygar, Legend of Kay, Shadow of Rome, Brave.

Also, after looking through my collection....

4x4 Evolution
Fire Blade
Tak & the Power of Ju Ju
The Suffering
Trigger Man
Antz Extreme Racing
The Boumcer
Spy Hunter

And another

Racing: Rumble Racing!
Seriously fun racing game.
