I could see some patches making the game decent.
>Fix shitty UE5 optimization
>Add NPC dialogue in the streets so it doesn't feel as lifeless and dead
>Open up some of the buildings, even just with basic ass interiors for more interesting exploration
>Add variable NPC encounters throughout the world even if just basic shit like Anarchs roaming around, or people having a party in a garage, or whatever
>Remove literally all motorcycles from outside because what kind of retard leaves a motorcycle in the snow
>ANY kind of reason to explore beyond shitty graffiti collectibles; ideally in the form of sidequests

Anything else would require a major patch/update I think. Also I know literally 0% of this will actually be done but a man can hope
