I have a private git copy of every recent open-source Switch emulator. I don’t have a use for them, for now at least, but at least their work won’t be lost.
I worked on a fork of another Open-Sourced MMO (forked from Ryzom Online). Lot of nice idea (like spell crafting, among other), but the tech stack and system was so old it was more a pain than anything. You couldn’t even jump in that games 😂.
Remaster -> Take same assets, enhance it (better textures, better shaders, etc.), add some QoL fixes (new hardware support, etc.), but the base (and most of the time the engine) stays the same. Remake -> Take same idea, redo it (new models, new technologies, etc.). May or may not have an engine change
Reboot -> Take same base, new ideas, and redo it (new models, new technologies, etc.). May or may not have an engine change
Edit :
A remaster example : Titan Quest Anniversary Edition -> Same game, remastered textures, add large screen support, among others.
A remake example : Oblivion Remastered (ironic name) -> New engine, new textures and models, but with globally the same idea.
A reboot example : DmC: Devil May Cry (the 2013 game)
