Counter strike is a multiplayer game, I’m talking about solo game (and even mp games can have difficulty accessibility options, like Tekken 8 does). About your target audience thing, I’d love to play dark souls and elden ring for the exploration, awesome music and ambiance but the difficulty and slow paced gameplay always put me off. Or to take the other example of Celeste, some people play it because of the difficulty and fun platforming, but I played it for the story and music and I loved it. Giving accessibility options will help people enjoy their game how they want with close to 0 additional development time cost.
