REmake. Still holds up incredibly well.
Amnesia was pretty cool, but the lack of a map was annoying in later parts of the game and it became quite easy to see through the enemies after some time. At one point, I just started letting myself get killed so I would respawn at a checkpoint closer to my goal, lol...
RE4 however is plagued with way too many superannoying action packed segments and it killed the series forever. Also, I consider survival horror to be a subgenre of (Action) Adventure. RE4 is a straightforward shooter.
I really hate the awkward contrast in that game. For example, at first you encounter an intense boss in the castle cellar, which really felt like the right step for horror games. Next thing you know, a minute after that you're throwing golems into lava like it was goddamn Lord of the Rings and participate in a ridiculous Indiana Jones Temple of Doom themepark. I love that game. But then, I must also hate it. :/
