If I turn off opportunities, they really shouldn't appear on my map. That's a big oversight.
I think the devs who work on this stuff are just too precious about the systems they create to let players turn them off. At best, the player's desire never to see or interact with this UI stuff probably doesn't even occur to them, and at worst they just don't want you to be able to ignore it. They spend months or years slavishly building stuff and people are like, "wtf is shit!? Gah turn off already".
Must be weird. Especially if you know Hitman (or whatever) and it's obvious you're building a crutch that is way too on the nose and undermines some of the core legacy mechanics (experimentation and solving the puzzles yourself). They get roasted for taking the franchise too linear, so now they widen it back up, but cannot resist the urge to draw a glowing fucking line for you to follow. I just get the impression they don't trust the core mechanics. They are finally building what people asked for, but they don't trust it, or the general audience with it. I think the general audience is often smarter than they get credit for.
That post might come off a little weird, but idk... these are my thoughts seeing the really overt, obtrusive way they push, label, remind, list, guide you toward opportunities and outright show you the answers to the puzzles with the challenges before you even take a step into the level!
You can turn most of it off (and it doesn't break the game thankfully) but I get the strong feeling they'd rather you not.
Or maybe I'm reading way too far into a glorified tutorial and crazy-talking about it. Which is entirely possible.
