In addition to the OP, Hitman 3 should have the larger briefcases (which are the only ones that can hold a sniper rifle) take a while to unlock. From the moment I started the game, I felt like I could almost immediately take any sniper rifle anywhere I wanted, because it took so little time to unlock the first sniper. This isn’t bad per say, as it allows for experimentation, but added in with the fact that there’s no briefcase size differences, it made it feel like the only hard part of sniping an enemy was finding a vantage point (and on occasion throwing the briefcase up a ladder, which was more dumb than it was a good challenge).
I just remember how fun it was trying to sneak a sniper past people in Hokkaido, having to care greatly about what agency pickup I selected for it, and having to find the perfect hiding place to snipe the targets. And I think the first few times you use a sniper, you should probably have to take up that stress as a challenge. Just my opinion though
