I feel you. Warmux was really neat. Sadly, it never got as much development as Hedgewars, even though the mascot theme was really cool. AFAIK, Warmux has been inactive (or at least extremely slow) for years, while Hedgewars has been thriving.

Touché.
Battle for Wesnoth
This one never gets the love it deserves. It's a fantastic turn based strategy game with multiple campaigns and storylines, multiplayer, and campaign design tools. It's an old project (started in 2003, IIRC), but it's still fantastic
Hedgewars
Basically, this is Worms but with adorable little hedgehogs instead of, well, worms. Single player is okay, and it has online multiplayer I guess, but the real fun (just like in Worms) is local multiplayer. Also, it has Portal Guns. There's really no downside to this one.

Re-volt io and RVGL
This one's a little iffy. Re-volt was a fantastic R / C racing game with bright graphics, fun tracks, excellent controls, and a killer soundtrack. For good or ill, it was put out by Acclaim, which self destructed in 2004. The Re-volt fan community, however, doesn't know the meaning of the word "quit."
Nowadays, you can join a lively community with regular online tournaments of the game. There's a new cross platform engine called RVGL (that's Re Volt Game Launcher), and metric tonnes of mods and fan content. You still need the original game's assets, though, which is where it's dicey; they're technically abandonware not open source, unless I'm mistaken.
Anyway, links!
Unciv
This project's aim is to be Civilization V, but with more abstract visuals, and, or course, free. In short, it's FreeCiv, but Civ V instead of II and a UI from the 2020s rather than the 80s. (Not throwing shade here; FreeCiv is an amazing project that is exactly what it wants to be!)
If that's not enough to keep ya' happy, I know a few more, but they've mostly been covered by other folks here.
Edit: formatting
I don't think anyone was suggesting NixOS, just the Nix package manager and repository, which will work on any distro. There's still a bit of a learning curve, but it's not as steep.
I try to avoid any kind of "ThiNG BAd" statements. They're just not helpful, and they tend to piss off anyone who likes the thing.
Thanks for not jumping on me, though. I really don't mean any offense, just trying to be helpful.
I feel weird recommending this movie because I fully acknowledge it's not exactly good, but...
The Man Who Knew Too Little (1997)
This has long been one of my all time favorite comedies. I've seen it probably a half dozen times, and it still makes me laugh out loud. Bill Murray is brilliant and Alfred Molina is clearly having the time of his life. I absolutely love it.
The AUR isn't a package manager. It's a package repository that you can use a package manager (on Manjaro it's probably pamac) to install from.
There really isn't a more extensive package repository than the AUR, and there's definitely not one for any Arch based distro. If the package hasn't been updated in a while, you might have to go to the project website and check for an alternative install method, like Flatpak, AppImage, or a precompiled binary.
ETA - someone pointed out Nix, which I had totally forgotten about. I feel like everything else I say here stands though.
As a side note, and I'm likely to get jumped on by Manjaro fans for this, but on Manjaro extensive use of the AUR can lead to system instability. This is because the official repos for Manjaro are out of sync with the Arch repos, and you can run into dependency problems.
Kinda also an indictment of how much we pay teachers and firefighters.
Just sayin'.
Sorry, mate; the dark mode not working is the only thing I've noticed as of now. I mean, I literally installed 39 yesterday, so I haven't really had a chance to dig in yet, but so far it's not an issue.
There are none, I'm afraid.
