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.

Addendum Source Ports for Android

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.

Oh, also ScummVM should always be included in such a list. It supports a ton of classic adventure games from LucasArts, Sierra and others. And by now even Might and Magic 4+5: World of Xeen.

Beside the already mentioned Open Source Game Clones there's also this list on GitHub.

As for specific titles, I'd like to add:

• Fallout Community Edition and Fallout 2 Community Edition
• VCMI (open-source engine for Heroes of Might and Magic III)
• OpenGOAL (port of Jax and Daxter, second and third game in development)
• OpenGothic (officially only supports Gothic 2 but works with the first game as well)
• Perfect Dark port
• Super Mario 64 Port
• TRX – Tomb Raider I & II: Community Edition

There's also WipeOut Phantom Edition but this one isn't open-source so I'll just leave it here in case someone wants to check out the existing build.

Addendum Console Games:

If you are looking for Ports for Console Games to PC here is this list on GitHub

Also i would recommend the Open Source Port of the First two Jake and Daxter games

Addendum Source Ports for Android

moonpiedumplings made a list of Source Ports for Android on reddit

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.

In the moment there are alphabetical sorted:

• 68 PC Games in total

I like this two but i try to keep it in the pc gaming Side, less the console Side. Mostly because i never Had a console;)

I mean you can only play them on PC, so I'm not really sure what you're saying here

Throw Manic Miners on there. It's a fan remake of the old Lego Rock Raiders game, and it's really fun. There's a custom level builder and I think there's a browser you can search for other custom levels.
