I’d say follow the guided story missions until you get comfortable. They’re very much “go here, do this” and are generally pretty fun. But then there’s a huge amount more to uncover on every map once you do the story stuff, which will now be way less intimidating since you’ve learned the map doing the story stuff. It’s a big sandbox and you’re rewarded for being creative. Take your time on each map, each one is almost its own game.
