Getting back into the game.

Hey guys, I've finished this game three times now. But I still can't seem to stop coming back to it.

I don't want to do another complete playthrough, so I was thinking is there something else that one can do in this game ?

For instance, I would love to make this game just a hunting simulator or something, where I just spend time preparing, buying the correct items and then going hunting in this game. I'm sure people already do that, but I've never done things like this properly in this game.

I am open to other ideas as well, I just need a different way of playing this beautiful game, not just focusing on the missions.

Thanks!

Btw, currently I am playing on a Xbox, so no mods are possible. But do let me know if there are some good mods, I do have it on steam as well. Maybe I'll install it on PC if there's something very good.
