I am looking for Obsidian game that was made in 1997.. Does it come with a different name with GOG because when I type the word Obsidian, it only shows up 2 different games?

Thanks

If you're asking about this:

https://www.mobygames.com/game/obsidian

Then you won't find it because GOG does not sell it.

GOG says Obsidian is one of the games I own; but it does not install. Why?

Not Obduction?

There's literally no game here by the name of Obsidian, and you managed to find a 1000 day old thread.
