I guess I’m confused then. They didn’t add features. Higher frame rates and resolutions aren’t new features, they’re just free additions that developers get from updated build processes. There’s no reason why those would “disqualify” them.

As for the other stuff, I don’t think the people who have already played these games are the target, as you suggest. Remasters are typically for people that didn’t play the original or missed it on its original system. Remakes are usually for existing players who want an updated experience.
