Here's a catalog that Night Dive can tackle: System 3. Which also encompasses the Epyx catalog. To what degree I have no idea, but hey it's worth a shot.

This just scratches the surface... here's hoping we can get all these fabulous games and replay them whenever we want.

It fucking well rocks.

Epyx also published Jumpman, one of the greatest platformers ever. It was a C64 release, but there have been DOS and Windows remakes and homages galore.

System 3? These guys:

They did some awesome games back in the day (The Last Ninja series and International Karate etc).

I had Jumpman, yeah. That one takes me back... Used to play the ___ Games games on my friend's C64.

Temple of Apshai I had and enjoyed, but one day I let a friend borrow it. While creating a save disk, he forgot to take the original disk out of the drive and accidentally formatted over the game. I never did get a new copy of it...

It culd be in interesting expetiment for GOG to bundle up these older games and sell them with 5 dollars or so. Though not all of them had a DOS/Windows version, so there's a lot of games in Epyx catalogue, that just wouldn't fit here.
