I found a "BBS on a CD" as a kid in the 90s. It was intended for people setting up a new BBS but it came with a good chunk of content to seed the system with.

Unfortunately, due to the nature of BBSes a lot of the stuff wasn't terribly useful for just one person. Emailing yourself isn't terribly useful. Door games were usually multiplayer, although LoRD was playable solo, and was in retrospect a precursor to games like Farmville.

The part where the BBS admin would call your number to verify your identity was real as well. It was always fun to explain to mom why some totally random guy was calling and asking for me.
