My mother's favourite game on Linux is without a doubt Frozen Bubble. It is a casual game in all of the best ways; one you can dive into and learn at your own pace thanks to its simple but repeatable formula. Consider this to be a snapshot in time back to 2002, from right before the game was to take the world by storm.
If you look at the commercial Linux gaming catalogue at the turn of the millennium, in amongst all of the 3D shooters and strategic simulations being released, one glaring omission seems to have been the lack of any racing games.

The most appealing aspect of my QDI Advance 5/133 motherboard is its inclusion of AGP, PCI, and ISA expansion slots. By having both dedicated MIDI and 3D acceleration hardware I can dip my toes into two different eras of gaming. As for the actual MIDI tracks produced, well, they have personality at least.
DevilutionX is a source available game engine source-port of the classic Diablo and Hellfire, updated for modern platforms and there's a new release out.
After being released for more than 10 years, VVVVVV is back with a big new version which follows on from the source code being released back in early 2020.
