(re: Sneak Peek CDs)
Regarding Sneak Peeks 2, though you could buy it separately from Sierra, it was at one stage included on the Imagination Network installation CD that came free with a variety of gaming magazines.
That’s how I got it.
The CD itself is black and came in a black envelope (both have Imagination Network printed on in white), along with a little manual.
Some people may have it and not even know it.
