I was looking for Riven today, and I came across several old games that I've never heard of. One was especially interesting. What caught my eye was the design on the disk. It was a horse-looking thing with talons. The game is called Stellar 7 and a search revealed that it's some sort of sci-fi computer game that was published in 1990. Unsurprisingly it doesn't work on my computer.
