Best single player game ever made?

[TrueBias]

Will give some HMs:
RDR2 (GTA games too obv, but RDR2 best rockstar game)

FF8 Ramaster (most replayable FF because of cards and junction system, has 3x speed)

The 3x speed is a godsend but I hate remasters. They're never worth it. REMAKES are where it's at!;

Just glad to have another FF8 fan. I can never decide if that is my favorite or ff10.
