Few of my favorite games are:
Legacy of Kain Series - The best dark n goth Vampire game ever with the best storyline. (Third-Person Action/Adventure)
Syberia I & 2 - The most beautiful adventure game. Beautiful story, graphics & cinematics! (Third Person Point n Click Adventure/Mystery)
Amnesia The Dark Descent - Spine chilling psychological horror game. Very few people may finish this game. (First Person Survival Horror/Mystery)
Penumbra - Overture, Black Plague, Requiem - Survival Horror game. Amazing! Very atmospheric...(Horror/Mystery)
Witcher 2: Assassins of Kings - Mind blowing graphics!! & great gameplay. Non linear gameplay. Can have different endings depending on the decisions you take. I liked Iorveth more than Geralt
(Third person Action Adventure/Hack n Slash)...
Severance: Blade of Darkness - Quite old, but the Best hack n slash game I've ever played. Awesome weapons with a lot of combos, Bloody combat, different levels ...just bloody fantastic.
Rayman Origins: Beautiful 2D side scroller game. Brilliant graphics n artwork. (But I still like the old Captain Claw game the most
)
Limbo: Fantastic 2D game. Gr8 Puzzles. Dark atmospheric, BW graphics with gr8 physics. Immersive gameplay..Fantastic levels! Finished it in 2 days.
Nikujin: A tiny hack n slash game but quite tough. Highly addictive once you get started. I finished it few times btw. Love it
