Well I've never heard of this one before, but since you said it was never officially published, maybe that's why. Did you play it when you were in Germany?
I think all the games I played on our first computer, the Apple ][+, were pirated. I didn't realize it then since I was such a little kid. All I know is my dad would bring home a box of floppy disks with games on them from time to time, and I'd play them. I didn't question it then, but now I wonder how he got them all?
