No... please don't touch my baby, Capcom.

Well I guess it's technically their baby, but I adopted it goddamnit.
Novelty is faaaaaar from what it is anyway. It's a watershed moment in gaming that basically created a new genre and is a certifiable classic. Capcom and others done admirably in refining the gameplay of the series for sure, but it's fine as is. We can play DMC5 if we want a game that plays like DMC5. Just leave the original alone, it isn't hurting anybody.
This is my biggest fear with any and all remakes. It won't be a big a problem for people like us, we have very sneaky ways to play the originals, but new players will probably go for the newest version of something. The amount of people who care about preservation is way less than the amount who just want to consume product with no hassle. That kind of thinking is why you have to jump through hoops and use fan restorations to see the original Star Wars trilogy without the icky Special Edition changes. But do you think anyone who streams them on Disney+ cares? Sure, a handful of people do, but most people just want to see the movies with as little hassle as possible. Anyway, I'm preaching to the choir. TL;DR: Fuck you George Lucas.
