And what institutional system incentivizes profit margin and cash grabs over doing things people like without charge? Again, it's just the gaming industry catching up to every other big, profit-driven industry and jumping full-bore onto the capitalism train.
For what it's worth, though, I'm with you - I enjoy skins and I have the money to enjoy them, but I hate that the focus is purely aesthetic and more companies aren't trying to just build great games that last instead of rereleasing the same game a thousand times or using games-as-a-service to make games an actual marketplace instead of just a game. I also wish the game was smoother and I hope it has its own Destiny-style glow-up.
