Hmmmmmm. Pretty tough. I'll name a few I guess.
2B (Nier Automata)
Geralt of Rivia (Witcher)
Arthur Morgan (RDR2)
Senua (Hellblade)
Rex & Pyra (Xenoblade Chronicles 2)
Amanda Ripley (Alien Isolation)
Some obscure underrated characters I thought were interesting and ended up really enjoying their personalities, back stories, etc
Henry of Skallitz (Kingdom Come Deliverance)
Dr. Johnathan Reid (Vampyr)
Sebastian Castellanos (Evil Within)
