big pet peeve in games with guns is when they really don't understand how sights work. sometimes the back is taller than the front, sometimes they don't line up and it drives me up the wall, sometimes the front post is just missing. there's a lot of ways people have fucked up sights in games
edit: this post was inspired by red dead redemption 2, they have all those I'm pretty sure. for those reasons and nausea related ones I don't use the first person mode at all
