PG, in my eyes, has never been interested in or never allowed to really explore the possibilities of their own open worlds. Other than very modest additions and content, the game is nearly the same, at its core, as the first title. Compare that to how Rockstar has massively expanded what players can do in their open worlds in the same time frame. For me, they have yet to deliver an open world that feels genuinely believable because there is only basic world logic and only superficial interaction (Smash board with car, cut-scene transition to mission or discoverable, robotic NPC behavior, etc). It's never immersive in a way that GTA or RDR or even the NFS open world games are. If the purpose of a game is to inhabit a character that inhabits a world with some degree of freedom, it has to be immersive or players disengage quickly, even if they are not fully conscious as to why. FH4 was the closest to an immersive experience thanks to the setting & seasons - you could squint and kind of almost pretend like you were there in England in the fall.
