Underapreciated games, What's on your list? Options

[unitself]

So, I was buying a used game today - Shadowman 2 - and I was thinking to myself, "I loved Shadowman 1 for the DC, I hope this game is just as fun." Which then caused me to ask tis question to you guys.

What do you think are some underapreciated games?
or even games that you like, for whatever reason, that really no one else liked
I know these questions are tired and old, but play along anyways.

My list -
Shadowman (DC).
Good adventure. Good story. Excellent and creepy sounds. Not too hard. Good length too.
You are this guy who's littel brother is killed and you get "cursed" to track down several serial killers. Part of your curse allows you to travel back and forth between the living world and the dead world.

Another one was this tank game called Wild Metal (DC).
It was slow as hell and not very exciting (ie: fast), but I played it all the time. Mediocre 3D graphics hurt the initial wow factor for most people I would imagine. Still, I loved it.
