I thought I'd start a thread about MUDs, MUCKs, MUSHs and everything in between. Post one of your favorites and tell us why.
Maybe, if anyone is interested, we could start a guild or clan on one of them.
Every so often I get a hankering to play a text-based MMO. They lack graphics, but have far more depth than the modern ones. They are free 99% of the time, but some allow you to buy credits for stuff (not my favorite type of MUD).
Right now, I just started playing Realms of Despair. It's considered to be one of the fathers, if not THE father, of Smaug-based MUDs. It's pretty fun, based on a sword & sorcery world, but not incredibly innovative. I'm using Portal to play. It's a very good, free MUD client.
I've also dabbled in RetroMud a little. The strong-point of this game is the massive number of classes and races. You first pick a basic class at first, like a Thief, but then around level 13 can extend your class to a related branch, like Assassin or swashbuckler. Races are extremely varied. There is a whale race and an insect-like race that has many limbs for carrying tons of stuff. The only thing that kept me away from RetroMud is that it sort of requires you to group a lot.
So what do you guys play?
