If you're talking accessibility because of disability or similar, then playing on PC is the way to go. There are "easy mode" mods for most FromSoft games that are on PC.

FromSoft games follow a sort of "vision" of how the game experience is supposed to be. It's a large part of what makes them such great games, but that mindset comes with the downside of less "accessibility", I guess.

But since people are beating their games one handed, on dance pads and rock band drum kits, how hard can they really be :)
