make sense, didn't check seleucids bonus

The hardest to compile is Spidermonkey 38 mainly because it relies on python 2. Spidermonkey has very few minor versions that are ABI (backward compatible) sometimes they even break it in minor like 76.3 and .5

I didn't really forget that. I've just assumed that those library versions were backwards-compatible (as they should be) and that he would need fewer libraries anyway since it's an older alpha release.  But yes, that is one issue you inevitably hit while learning to compile. And this knowledge ia quite valuable in today's world. 

@Dunedan Good. If compiling older versions of 0ad is as you describe, there's another way. Probably easier than compiling. In Debian, version 23.1 of 0ad was available in Bullseye (11.x). 1. Install Debian 11 Bullseye on a USB stick just like you would on a hard drive. https://cdimage.debian.org/cdimage/archive/11.11.0/amd64/iso-dvd/ 2. Run the installed Bullseye from the USB stick on your computer. Of course, unless it's a recent computer that the Bullseye kernel (5.10.x) can't handle. 3. Since the Bullseye repository is already down (I think), 0ad and its dependencies (there aren't many) must be installed manually. https://packages.debian.org/bullseye/0ad The standard command: apt install 0ad will not work. 4. Download the following: http://ftp.de.debian.org/debian/pool/main/0/0ad/0ad_0.0.23.1-5+b1_amd64.deb http://ftp.de.debian.org/debian/pool/main/0/0ad-data/0ad-data_0.0.23.1-1.1_all.deb http://ftp.de.debian.org/debian/pool/main/0/0ad-data/0ad-data-common_0.0.23.1-1.1_all.deb 5. Try to install it: dpkg -i 0ad-data_0.0.23.1-1.1_all.deb dpkg -i 0ad-data-common_0.0.23.1-1.1_all.deb dpkg -i 0ad_0.0.23.1-5+b1_amd64.deb We're taking a look at what dpkg outputted. The first two packages should install correctly, unless some fonts are missing, in which case they need to be installed. https://packages.debian.org/bullseye/0ad-data-common The last command will be the hardest, as dpkg will output something like: "error – package xxx is missing". You'll need to download this package manually, install it, and try again: dpkg -i 0ad_0.0.23.1-5+b1_amd64.deb And so on until you succeed. After a few rounds of this, we have 0ad ver. 23.1 installed for good. Now you can run 0ad and finally put the Bullseye + 0ad USB stick away. Best regards. Happy New Year

Wonder if we could split it in multiple buildings with different purposes. Else that will be a scenario only actor.
