Meh. FF7 stands up fine on it's own, even though the overworld characters look like crap. Goldeneye is fine, even with the controls being what they are. I don't see the point in "preserving" old games if they're going to be radically different.

I just finished playing the original NES Metroid and the GBA remake back to back; they may as well be different games. And, sure, there are lots of QOL improvements but the whole point of me going back and playing the original Metroid was to see how the series started and how subsequent games improved on the experience.

And it was really interesting to see how they created replay and challenge. In the original, you couldn't aim down or crouch so you actually had to plan how to deal with enemies that were short in a way you just didn't in the remake. There was no map (and they loved to make nearly identical rooms) so you may want to think about getting a piece of paper. And you started every life fron 30 health, regardless of how many energy tanks you'd found. These elements, while somewhat tedious after a while, were actually pretty refreshing in a world where every game has to hold your hand every single step of the way (see Metroid Fusion to Metroid Prime 4).

All this makes the game more challenging and that was the point. If you "fixed" it, it wouldn't be the same game, which was what happened. It became a cheap Metroid knockoff; without the innovations of Metroid 2 or Super Metroid but also not an accurate portrayal of the game that inspired them.

The only concession I'll make is emulator tools like save states. Once I beat Metroid, I was able to beat it again in an hour without dying once, but I never would have figured it all out without save states at first; it's just too grindy.
