Underappreciated great games

So this came from a mention of Legend of the Dragoon in another thread, what are some great games that deserved sequels but didnt get them, or great games that are just fairly unknown?


Heres a few of my favorite games that never hit it big enough.

Jet Set Radio Future/Jet Grind Radio

Basically you play as a bunch of kids rollerblading around Shibuya, with Tony Hawk style gameplay, but you're doing missions and putting graffiti everywhere you possibly can, the story was quirky, the music was crazy, graffiti was fun, and it was an all around great game, it was a sequel to Jet Grind Radio for Dreamcast, but it should have gone on more.

Originally a Dreamcast game, and one of the best titles on Dreamcast for sure, it did well enough for a port to gamecube, but the sequel that was in the works got canceled, it was a great RPG, if you can stand the outdated graphics, the story was epic, lots of depth to the gameplay, and Ship fights were amazingly entertaining. There was also lots to go back for after you beat the game, one of my top 10 RPGs for sure.
