Assassin's Creed, DA:I, Far Cry, Horizon, Tomb Raider, Wildlands, etc... sooo many games use this formula. I'm not going to argue that it's necessarily a bad formula. Because I think there's merit in the mindless fun of going from spot to spot and clearing it out. But personally, I do think it's the antithesis of what a great open world game is. When everything is marked on the map, or too samey, when there's nothing to look forward too: no interesting quests, or characters, or random encounters, or useful loot, etc... then there's no genuine sense of adventure. It's a check-list.
