Interview with Judith Pintar at The Digital Antiquarian
Wow, Cosmoserve sounds really interesting.
It's really worth a try! I really like how it switches back and forth between the physical reality that the protagonist lives in, and the suprisingly detailed MS-DOS simulation. It's pretty astounding what it manages to do with the AGS engine.
You can play Cosmoserve on the Internet Archive in your browser, of course!
(I wonder if I still have the atrocious AGS game I made as a preteen somewhere...)
