Zelda: Majora's Mask - My favorite genre is semi-open action adventure's like this. I love Zelda. This has the best atmosphere in the series, going for something almost nightmarish even if still innocent. The groundhog day mechanic allows for a world of many fullfledged characters whose stories can be played with. Everything ends on a depressing note.
Resident Evil Remake - Maybe the only legit throughout "scary" RE game before 7. Silent Hill was always the scariest, but man, Resident Evil just has so much better level design.
Killer 7 - I keep thinking about this shit until today. I feel safe to say that there's literally nothing like it. It makes Lynch movies look tame - absolutely no punches pulled. The presentaiton would lend itself extremely well for an HD remaster, but I'm not holding my breath.
Bloodborne - The first HD game I felt confident in saying that it's in my top 10. A classic horror fan's dream when it comes to presentation (I just wish there was a few more levels with bg music). Amazing level design/gameplay undermines its feeling.
Godhand - I don't know how you can make a 15 hour beat'em'up not feel stale at any point in time. Game just keeps throwing new challenges at you at all times. Always challenging, alway gotta adapt. You fight a gorilla in a wrestling costume.
Paper Mario: Thousand Year Door - Amazingly creative Super Mario adventure. Could feel stale if you played the first one recently, but in the end it's shinier than the latter. It's funny, but also still takes itself serious enough compared to Mario & Luigi.
Super Metroid - Unbelievable level design and the atmosphere it could pull off is still mindblowing.
Skies of Arcadia: Legends- Pure adventure. Feels like you've actually discovered a whole world by the end.
Okami - I can overlook its overblown handholding because of everything else.
Nier - I haven't played this too long ago, so I don't know if it would stay here after I digested it more? I absolutely didn't get ohters gripes with the gameplay. Felt like a very competent (more actioney) Zelda-clone with awesome variety. GOAT soundtrack, great use of the medium to tell a (super depressing) narrative. Rough around the edges, but only the sidequests are really bad.
excluding handhelds games, otherwise I can't handle this.
