Pygame
🐍🎮 pygame (the library) is a Free and Open Source python programming language library for making multimedia applications like games built on top of the excellent SDL library. C, Python, Native, OpenGL.
I initially considered Pygame, but a quick discussion with ChatGPT convinced me that Godot would be a better, more portable option for my case.

I don't know If I can be very helpful, I'm using gen2brain's binding [1].
I started about a year ago asking the AI very beginner questions about Go and 3d math. I think it did steer me down some wrong path sometimes and of course I did some dumb things myself too. I'm not using Agents, just asking questions about features, then writing the code myself by hand.
I really like the power of the tools and the constraints of the language in Go. It's been fun so far.

It's interesting you would mention Odin because I spend a fair amount of time playing with it as well. It was easy to get started and fun. Fast, easy to iterate. The reason I moved away was not the language itself, but I felt it was too much Ginger Bills baby.

dxwrapper
Fixes compatibility issues with older games running on Windows 10/11 by wrapping DirectX dlls. Also allows loading custom libraries with the file extension .asi into game processes.
>I only wish Wine also allowed me to zoom 2x or 3x, but this is where Gamescope comes in
Also possible using dxwrapper (for DirectX 7-9 games):
https://github.com/elishacloud/dxwrapper
Similarly to dxvk, you drop a few DLLs into the game directory then edit one config file. No need to use a dedicated program.

pygame-ce
🐍🎮 pygame - Community Edition is a FOSS Python library for multimedia applications (like games). Built on top of the excellent SDL library.

HandmadeMath
A simple math library for games and computer graphics. Compatible with both C and C++. Public domain and easy to modify.
sp_math.h is, as noted at the top of the file, a repackaging of https://github.com/HandmadeMath/HandmadeMath
It is not part of the core library. It is certainly not meant as a reference-level implementation of math functions. It's there so you can write an easing function for a game without pulling in libc. It seems like its existence has offended you. If that's the case...I'm sorry? At every possible point, I note as loudly as possible exactly what that library is. I found your tone extremely dismissive and disrespectful and I don't care to engage with that any more than I already have.

Project mention: Dungeon KeeperFX 1.4.0 with Multiplayer Released | news.ycombinator.com | 2026-07-05
The "Further Improvements" section on the README mentions "Native cross-platform support": https://github.com/dkfans/keeperfx
It seems like it currently runs pretty well under Wine though.
