It's very common for people to talk about what games they'd love to see remade with modern technology and gameplay changes, such as taking the old RE games which used fixed camera angels and tank controls and updating them to have real time visuals that look even better than the pre-rendered backgrounds of old and modern control schemes. But what are some games that you feel are so timeless that you feel a remake isn't really necessary? (though remember "remake" is NOT the same thing as "remaster," remaking a game typically involves making major changes to both visuals and gameplay, while remastering means leaving the core gameplay and structure alone but making the visuals look a bit nicer for more modern displays, like Bioshock Remastered doesn't make any changes to the visual design, gameplay, and level design, it just makes the textures and effects look a bit nicer than they did back in 2007)
While I'm not sure if I'm necessarily of this opinion, the two most common games I tend to see people bring up in this sort of discussion are Super Metroid and Resident Evil 4. Super Metroid's sprite based visuals have aged well enough that people feel it doesn't really need that much of a visual update unless the developers redid the game with hand drawn visuals similar to something like Skullgirls, as I've seen people say things like "Metroid 2 going 2.5D for the Samus Returns remake was fine because the visuals of the original don't hold up that great compared to other games of that time period and plus we've now a got an official color update to the game, but Super going 2.5D might not look as visually appealing unless the game has extremely well done art direction." Also Super is already held in high regard for having good controls and level design so it seems like people don't want those to be touched too much.
In the case of RE4 the most common thing I hear is "RE4 already has such great pacing and a nice mix of action, horror, and cheesy b-movie moments, that I worry a remake might lose some of that charm." Plus RE4 already introduced a more modern control scheme to the series so it's not like the game needs much of an update in terms of play control like the older games that used tank controls.
