It's not finished yet but OpenXray Gunslinger is probably going to be a better STALKER: Call of Pripyat remaster than the official one that just got announced.

Disclaimer: I changed a little the layout and thanks for the contributions!

The Idea:

On my old Mastodon Profile i've made a list of Rebuilds/Fan Remakes/SourcePorts (when possible opensource, no commercial remakes) for old PC Games, and i want to share it here on Lemmy too, so people can easily find it.

Why?

I've played lot of these games, and i'm glad there a Fans who still working on these games, to make it accessible on modern systems and giving them some QoL improvments.
In my opinion, that's a great way to preserve old games from being forgotten and keep playable for new players.
Also these people need some recognition (at least) for their hard work.

I'm glad If you help to complete this list and contribute some games you know.

How come there's no mention of 0.A.D, it has amazing graphics, at least from the videos and screenshots.
Haven't gotten a chance to play it unfortunately.

Do you mean https://openrct2.io/? That's already on the list

Whole Lee Shit jazz jackrabbit brings back memories. I remember my first time playing it at a friend of the family's house, there was a dude there talking shit about how Windows was for lazy people (I was very young and windows was still kinda newish)

But how dare you not include OpenMW! Imagine having an og Xbox masterpiece on your phone, and you can mod it!

Widelands - Settlers II inspired game, played a couple of hours, pretty neat.

FreeCIV - how can that gme be missing here?

UnCIV - Civ V clone, also pretty neat

It was already on the list (TES III: Morrowind)

Morrowind: https://openmw.org/

Is already on the list

Star Wars Jedi Knight I and II: Jedi Academy and Jedi Outcast (Not stable) - OpenJK https://github.com/JACoders/OpenJK

Despite the official name being "Jedi Knight: Jedi Academy" it is not Jedi Knight I. It is actually a sequel to Jedi Knight II: Jedi Outcast. It came out only a year after JO and was announced in April. At first I thought it was an April Fool's joke because the screenshots looked like something that could easily be made with the mod tools at the time.

It wasn't called Jedi Knight III because you play a different character.

Anyways, the real Jedi Knight I was "Jedi Knight: Dark Forces II". An open source implementation is available at https://github.com/shinyquagsire23/OpenJKDF2

And to round it off, the open source implementation of Dark Forces is available at https://theforceengine.github.io/. I think it even supports the remaster.

I actually really appreciate someone clarifying the chronology of these games, I've got them all in my steam library and can never remember the order they go in.

Do the OS remakes have any QoL improvements? I tried playing through them recently and had a very hard time with the manual save system since I'm used to autosave points in linear games like that.

As far as I know they don't add autosaves. I think the priority was things like proper wide-screen support and higher resolutions for the older games.
