Here I keep track of free software I recommend trying.

Linux

Distributions

• Debian - Still remains one of my favorites in the GNU+Linux world. Very stable, well organized and maintained. Well supported by 3rd parties and has good free software policies. Great for servers and desktops.
• openSUSE Tumbleweed or Aeon - Excellent rolling desktops, both very reliable. Excellent for workstations on more cutting-edge hardware.
• GNU Guix System - A very different system. Very fun to hack on but a little challenging for the average user. This one is mostly for the Lisp hackers!

Package managers

• GNU Guix - Not to be confused with Guix System, it works as a package manager for any distribution. Quite user friendly and works great for getting extra software.

Games

I don’t play a lot of games but I enjoyed some of these. I haven’t played them all yet!

• SuperTuxKart - a really fun kart racing game
• The Battle for Wesnoth - a solid strategy game
• OpenArena - old school arena shooter
• Xonotic - a more modern arena shooter
• DCSS, Brogue, Nethack, ToME - roguelike dungeon crawlers
• Teeworlds/DDNet - a multiplayer platformer
• Veloren - voxel MMORPG
