A bit off-topic, but not too much: an old videogame from the mid 90s called Master of Magic (his author, Andy Barcia, also created Master of Orion, 40+ years old in the thread would probably know at least one of these two masterpieces) at some point got a big quasi-remake based on (allegedly) the availability of the source code, it's called Caster of Magic [0] and it's essentially a huge mod that changes a ton of things in the game, and fixes several bugs.
I was a big MoM fan when I was a kid and I followed this development with a lot of curiosity.
I found it interesting that a game which is now more than 25 years old managed to get a thriving modding community, given that modding games wasn't really a thing long ago.
By the way, there's a proper remake in the works, coming out in a couple of months.
Sounds similar to the story of how Transport Tycoon and Rollercoaster Tycoon received patches, particularly thanks to them being made in Assembler from the start and thus easy-ish to modify.
Though plenty of old favorite games in fact get fan patches, especially for graphics—e.g. System Shock (iirc) and original Deus Ex.
