You should probably mention that you only want games for which PC versions exist in the initial post.
(I could note that Questron 1 is in the same situation as Eternal Dagger.)
Yeah, you are right - that should exist. However I do wonder if I should also allow other types of home computers (Amiga, Commodore 64, etc.) - but that is a future discussion, and one to have for a possible revamp of the list (such as moving over to a Google Docs for example).
For now tho, thank you for your input!
Edit: If you count non-PC home computers, the question is whether you'd count home computers that were not released in the west, or that are not as common, as then one could argue that Ys 3: Wanderers of Ys would qualify, as it was originally released for Japanese home computers and is actually very different from its remake (Oath in Felghana), which is available on gog.
