I Picked up another Odyssey off of eBay recently and it came with a "complete" copy of the game Percepts.
I am using the word "complete" in quotes because Percepts never had a box, it was a send away title. It did have a brown cardboard box that it was shipped in, which I do not have.
What I have are the overlays, all thirty game cards and the instructions, which is the complete game. It works with Game Card #2.
The guide has it as being valued at $100. I am not sure if I want to part with it, but I want to see if anyone is interested first.
Make me an offer if you are.
