Not the person you're replying to, but the original Witcher felt fine to me too, but I'm a lifelong PC gamer and the interface/controls reminded me of older PC-only CRPGs like Summoner or even Neverwinter Nights. I love those games, but in terms of their control schemes they do feel clunky compared to the more visceral controller-optimized and streamlined Action RPG controls of The Witcher 2 and 3.

In other words, the first Witcher game is in more of a niche genre with significantly less mainstream appeal in terms of gameplay and UI.
