Nothing beats Tradewars2002 but Legend of the Red Dragon, Barren Realms Elite, and Usurper come close.

They were played on dialup, and later (including now by a select few), telnet or ssh enabled Bulletin Board Systems.

If you think 'hey this relaying of content around on horizontally organized systems thing is cool' you owe it to yourself to look into the history of FIDONet -- basically Nostr for the 1980s and early 90's. Similar to Usenet but even less central authority as it was hobbyist built.

If you want to go down a crazy retro rabbit hole there are worse places to start than https://www.synchro.net, which still provides a cross platform BBS server solution that can handle FIDONet, dos door games, and even dialup networking with a little elbow grease.
