I'll agree Witcher 3 is one of the all time best/favorite games of mine. Honestly I can't choose one, but have been playing shitloads of games with the PS+ Extra tier, think I've only purchased 2-3 games in the last year. I've played Hogwarts Legacy, Horizon Forbidden West, Mass Effect Andromeda, Control, Alan Wake, Call of C'thulu, almost all of the Assassins Creed games, most of the Yakuza series, Cyberpunk and so much more.
Having a blast right with the new Spider-Man 2 game on the PS5. It feels like Batman Arkham City. As you can now glide through the city and web sling. Avoiding most of the story and just swinging around fighting crimes and doing the side quests
