100%, like other people said just change keybinds. I’ve beaten dark souls 1 and 2 with KBAM and gotten a fair bit of the way through DS3 and Elden Ring with keyboard and mouse (KBAM) too. If you aren’t used to playing with KBAM you might have issues figuring out what to bind stuff to, and even then you might get frustrated at first (I quit DS2 initially) but it’s definitely doable. IMO KBAM is much easier for these kinds of games (3rd and 1st person) than a controller once you’re used to it.
