As you probably already know, there exist several unofficial Mageia repositories, maintained by enthusiasts .
I know 5 of them, and hope you'll find something useful there, which will justify the work of their maintainers.
So, in alphabetical order of the countries of origin:
1. Czech Republic
http://petos.cz/rpms/mageia-1
For 32- and 64-bit distributions, contains many games, but not only them (for example, clementine-1.0.1 is available). Has a list of the packages with brief description, but it looks like everything is in Czech. Additional repos for Mandriva are available as well. However, I did not find out how to download separate packages manually...
2. Greece.
http://mageia-gr.org/
A repo with minimalistic design, assorted 32- and 64-bit packages. Links to the Greek Mageia subforum page if I understood it correctly. Also available are ISOs of CD versions of some "openrp-1.0.3-KDE4" distribution, international and Greek, 32-bit only. I think the guys from the Greek sub-forum should know about it more...
3. Poland.
http://repo.mageia.org.pl/
Serious guys... have separate stable and testing 32- and 64-bit repositories - great respect for that. As far as I could see, no package description and everything is in Polish. Also their own "The Magic Remix" distribution is available.
4. Russia.
http://mageia1.ru/
A set of various packages (32- and 64-bit) with brief descriptions in Russian AND English. Mostly office- , multimedia- and communication-oriented (contains cuneiform, yagf, goldendict, deluge, IMs and players).
5. Spain (?)
ftp://ftp.blogdrake.net/mageia/mageia1/
This repo is probably the biggest one of all 5. No descriptions, just a list of packages (32- and 64-bit). Looks like it's been around for rather a long time. If you visit http://blogdrake.net/ and speak Spanish, you'll find lots of interesting on Mageia1 and Mandriva 2011.
So here they are and good luck! But, guys, if anything from the above mentioned repos doesn't work as expected or does something bad to your system - you know who is to blame and who is not .
