Explore a world. Kill things. Gain skills. Cities is a new multiplayer game from TotL, designed to take about 20 minutes a day to play.
Cities is a MUD-style adventure game with a graphical front-end, played in a web browser. Although ostensibly set in a fantasy world, there are major elements from a wide range of genres present in the setting. Many of these are (usually humorous) references to popular culture.
The community of players is supported by an interlinked wiki and a dedicated IRC channel.
