Ultimately, the only real way to preserve videogames is through emulation, whether through official means or not. Remakes can't ever serve that purpose because we can't remake everything. Remakes should be reserved for when creatives believe they have a new and exciting take on the same ideas.
Heading into work so I'm gonna boil down my thoughts ALOT. Our disagreement comes down to me misunderstanding your argument. My definitions as an analogue to movies: Emulator: Movie on a different projector Port/Remake: Movie on DVD, with bonus features Remaster: The Lion King 2019 vs original
I think all three of those categories have a right to exist, especially if they are, in some way, different to the original. Otherwise, why bother recreating a work at all? I bought SotC for the PS3/4 because those were the consoles I had to play it on, and because I liked the graphical updates.
But yeah. I encourage people to not buy things they dont agree with. If you don't like remakes in general, more power to you :)
