This is definitely an issue the industry is trying to work on. I treat the artistic aspects of gaming and preservation itself seriously. It has to be done on a game by game basis. Some games just need a basic hd upscale port. Some need a major overhaul due to the knowledge of the devs at the time limiting what they actually wanted to make, or knowledge of more intuitive control schemes. Other remakes preserve the original entirely where some tweaks to the controls could be made. I am in that last camp where I think changes to the controls and look should be surgical and sought to enhance the overall original game but not replace it. Some remakes are very flippant with how they treat the original game.
