You have been warned. Here, you'll find anything you might be interested in when it comes to games. Then you are ready to enter a new universe. The MUD can be entered by a large number of players at the same time. Usually you can chat freely with any other player in the dungeon, which makes the game a social place to meet your friends in as well as a game.
Different MUDs have different policies about chatting, though.
I am a coder at one MUD and play a couple of others off and on. After playing MUDs for a couple of years, I got the opportunity to become a coder, and later an arch, at Split Infinity. This MUD is very new, and opened to players fairly recently. VargonMUD's Home Page Vargon is a strange place, with the largest amount of crazy emotes I've ever seen anywhere, and lots of friendly players.
