Last Rites
Suggestion to devs: DOSBOX on Linux...
... exists. Just saying.

Package it properly for your DOS games so they run on linux without users installing dosbox on their linux PCs by themselves. Zero reason to keep those steam releases of good old games as windows only when they weren't for windows in the first place. Also I imagine people who use toasters as PCs (and thus prefer linux) and people who are interested in ancient games are often the same people.
