looking for something with bad vibes and a good story, games with a similar feel to:
-
Drakengard 1
-
Silent Hill 2
-
Signalis.
-
Spec ops: The line
-
Hotline Miami
edit: to be more specific, looking for something with that "Heart of Darkness" decent into madness vibe
Shin Megami Tensei, especially 1 and 3 (I have not played V. II is great too, but the tone is different) & the first three/four (2 has two parts) Persona games (yes, really - 1 & 2 don't have the social sim aspects and 3's story is dark, even if a bit of a slow burn).
The first Bioshock game.
Deus Ex (The first one. Human Revolution is also pretty good)
Half-Life 1 (or Black Mesa, the remake)
Bonus:
Vampire the Masquerade: Bloodlines. It's both dark in tone and really cheesy at the same time, good stuff.
