I understood that games catalog is not really important under linux. And it's quite difficult to find games in RPM format for mandrake 9.1.

Do you have an idea where i could find some games ( like Unreal Tournament, Counter Strike ... ) for the Mandrake distro or for others ?

As Mandrake 9.1 is new user oriented, Am i right to say that it is the best distro to play with ? How about another distro ? ( Suse, Redhat, Aurox ) ?

Try searching for a game using www.google.com/linux. I did and one site it gave me was linux.tucows.com, which probably has many games. Unreal Tournament's site for linux is www.unrealtournament.com/linux.

If the games don't come in RPM format, then try installing them from the source code (usually packed into a tar/tar.gz/tar.bz2 archive). It is a bit tricky, but most of the archives contain README and INSTALL files which help (sometimes).

If the games are available as source code, then I dont see why one distro would be better than the other, unless maybe one distro has newer/more drivers for graphics cards.

You're unlikely to find a game like UT2003 as an RPM. The files are distributed from the site as .bin files - you will need to make it executable (chmod +x filename.bin) and then (as root) run the file to install it.
