- mud.simauria.org 23 http://www.simauria.org/ -- This game was cute and quaint 5 years ago but now you can't get past the email verification anymore. I've messaged the admin email for this site a few times over the years asking if I can archive the server code but I don't think anyone ever receives it
- cyberlife.es 7777 https://www.cyberlife.es/ -- Logged into this just a few weeks ago to test charset support on my hobby mud client. It's a real life Madrid-like world mostly geared towards roleplaying I think (no combat). When I logged in as Sindulfo, someone said my name sounded like a butler and if there also existed a Condulfo. Was kinda funny to chat with them.
Sucks to know the source code for these servers will all get lost forever.
On Cyberlife, there's more than Madrid, but you need to get a vehicle.
Also, on MUDs, I do the same as a native Spanish speaker but in English, with Cybersphere, as reading almost technical English it's just "Tuesday" to me.
