Blizzard recently released Starcraft: Remastered on the 20th anniversary of Starcraft (https://starcraft.com). Because much of the game balance relies on weird/buggy unit behavior, it was critical to keep the game code intact, so the developers only focused on a graphical, UI, and netcode refresh. It worked, and was successful, but it's been months since release and there are still huge bugs and general problems with everything they did touch.

There was some discussion here about the effort it took to emulate a lot of the bugs in order to keep the game the same.

It's almost like we should take the old assets, take the new assets, run the exact old engine with the old assets, and then ON TOP OF THAT, let a Machine Learning system figure out how to, in real time, make the graphics look better.

Hey, Károly Zsolnai-Fehér (Two-Minute Papers), can you find someone to implement this?!? kthxbai!

You may want to look at https://github.com/falltergeist/falltergeist, though I didn't have the time to try it myself yet.

This does not seem like a graphics and UI update, just like a recreation of the original with FOSS software.

For anything you want, it's worth at least taking a look here:
