Some games will even give guns "recoil" that's totally fake, just to make them feel more powerful to the player. It doesn't effect the bullets but the visual conveys "stronk!"

Theres a famous example, i can't recall which game, but players complained that one gun was too weak and needed buffs. The devs said "okay, we fixed it" and players declared it the best thing ever. Behind the scenes the only thing that was changed was to give it a punchier, more satisfying sound effect.
