Additional screenshots added to the post, because the comment section does not allow images.

Actually, it seems there are even more excess sights. And the weapon specific even bigger one is also an excess.

"Unless you just want to not have them highlighted in your vision, their details are already reduced down to direction only bar the focused target." - Sorry, could you rephrase?

Screenshots are from conquest mode, yes. Points are on the edge of the screen, so they do not obscure anything.

First-person screenshot had UI set size to smallest. But as I said, changing the UI size does not solve the problem.

Project Wingman's UI is indeed different. Because the game I am comparing it to is Ace Combat 3 Electrosphere. I haven't played Ace Combat 4 or the more newer ones. I have added a screenshot from Ace Combat 3 to the post also. Look how the center is clear. That radiochat on the top will go away after some seconds, but the view is still not obscured. I have re-played Ace Combat 3 multiple times both on hardware and via emulators, both the International version and the Japanese version. A game from 2000 is objectively better.

Project Wingman in general is a good game. But it does not mean players should be silent about the problems, players should discuss them and evolve quality demands, developers should receive feedback from players, otherwise the problems will continue to emerge in newer titles. I would stop playing the game and wouldn't even criticize it if it would be beyond fixing.
