I didn’t say there weren’t, I said that most players (ie your average “fresh player”) don’t care enough to get invested… particularly given that the series has moved more and more away from “just shoot people to kill them” (like it was the first three games) and more into providing a wide variety of murder options (poison, accidents, explosions, making other people shoot them, etc).
The title is “Hitman” not “Gun Collector With Dangerous Job”
On top of that, such over emphasis on weapons can easily create more issues with people wanting to know why doesn’t the game have realistic bullet physics, bigger maps so they can have full bullet drop effect, etc. It distracts from your goal to murder people.
Do these come vetted by copyright lawyers to ensure no licensing issues? No.
Are they likely to be able to pass any legal expenses on to the creator? Nope… they’re probably broke.
Do these have animations included and guarantees of consistent interaction with Glacier 2.0? No
Do these skins necessarily fit the art style for the rest of Hitman? No
Are these going to be seen as unique items worth collecting in the game? No, they’re going to look like assets from any company that pre-buys assets.
Do these address the animation issues in fitting to character rigging and animations? No.
Are they even guaranteed to be consistent quality between models? No.
Buying 3D party assets off a random storefront is fine for people doing hobby projects, indie games or ones where the art style factors into zero percent of the appeal - but it quickly gets very dull and comes with a whole host of issues. A “fresh player” is vastly more likely to be put off by a gun that doesn’t fit in with the rest of the aesthetic than he is to by having a two versions of the same gun but with a pink sticker.
Guns are complex machines that are alien objects to most folks… and weird sacred objects to others.
