Following this logic whole human life is a puzzle game.

I still prefer 7z for compression

7z was developed in 1999. As far as I know, rar was popular due to was shareware with practically unlimited “trial” and there was an opinion, that paid products are better.

7z can be at least decompressed in macOS & FreeBSD out of the box.

On windows tar.bz/gz/xz unpacks to tar and then to actual files. As tar is a separate archive format

7z has way better (ultra) compression

7z uses proprietary rar library to unpack

Thank you for sharing the source in the first place.

I personally prefer projects/libraries with more permissive licenses than AGPL.

In terms of reinventing wheels… you precisely told why people do that: learning an engine. I’d use it to create an offline version of my favourite card games, but also, how to discover others think during game development. Latter for me is also important if I’d like to understand mindset how to create things more effectively.

About support… it’s actually hard to say what do you want to achieve. Making an app, library, a game by yourself? Sharing achieved results with community? Find others who can enjoy to create a game in a team with less requirements as there’s in companies?
