I think the selfish desire for remakes are insulting to the products loved by many and also to the people who made them. Like some Fallout 3 fanboys who didn't know anything about Fallout 1 and 2, newer generations will only remember the remakes and won't even realize how shitty they actually are.
I've always loved Jagged Alliance 2, for instance, but I'd never want a Jagged Alliance 2 remake, even though for all these years I've desperately wanted a modern game to take its place. I just hate remakes, they are nothing but a proof of laziness and lack of imagination. Just a pathetic money grab.
I have no problem with remakes if they are just like I mentioned before: just have the game updated to run on modern machines, optimized, modern resolution, bugs patched, better models/graphics if needed, clunky and bad controls "fixed", proofread and edited text, improved sound quality, x64 exe's, modding tools or better modding tools (if needed).
The problem is pretty much every remake ever made add stuff that it shouldn't, make the graphics even worst that the original, change the game "system" somehow (for example if someone remade Fallout 1 and changed what the SPECIAL attributes affect), make unnecessary balancing (making the remake easier or harder than the original), etc.
So the remakes I would like to see are unavailable in the real world.
For example, If the first Wasteland game got a remake and it was exactly the same but running on modern machines out of the box, high definition music and sound, high resolution support, bugs fixed, some grammar fixed and (not necessary but for those that wanted it) with an option to play with modern graphics. I bet it would pull plenty of newer and older players to enjoy the game now. As it stands, even many old players do not play that game anymore due to the need to use external software (DOSBox) and being quite a "clunky" game.
Another game that would see more love would, for example, be TES Arena, the controls are so awful that it is the only TES game before Skyrim that I never finished. If a remake would be made with better controls, bugs fixed, better quality music and sound, run out of the box without the need for DOSBox, support for high resolutions, etc. People could enjoy playing it now.
Some games, while great, didn't age very well and are a pain to make it run on modern hardware, if a remake was made, those games would receive more love again and more old and new people could enjoy them.
I am also of the opinion that any remake should come with the original game so people can play the classic version anytime they want to.
After all, when art pieces get faded or break, people restore them so newer generations can still appreciate them.
