As I was going through the CD's at a goodwill I came across 2 discs of what looked to be a set(Volumes 1 and 4 I think I saw), I assume they were educational games but they said not for sale(or commercial sale(something like that)) I didn't pick them up for the sole reason that I had no idea if they were anything special.
Can anyone tell me what they are(even though my description isn't the greatest)?
