Disclosure: GOG sent over copies for me to ensure they work.
As usual, the Linux versions come with their pretty installers powered by MojoSetup, this gives you the game plus a pre-packaged version of DOSBox to enable pretty much out of the box gameplay. You don't have to use the DOSBox they come with of course, you can just take them right out of the install folder and put them wherever you want, to play with your system-installed version of DOSBox. It's your choice, since they're DRM free.
I tested them and they work without issues:
Fantastic to see more classic games arrive with pre-packaged Linux support, so that Linux gamers don't miss out on some truly retro games. As I've said before numerous times by now, I consider keeping classic games alive, playable and legally purchasable a very important job. Not just to preserve the history of gaming, but some retro titles really are quite amazing.
