There are no races besides human, no stats, and no skills. Combat is standard, and there are few spells. On the plus side, the quests that do exist are well-done and difficult. There are also many smaller tasks that, while not quests, are often rather challenging. Coupled with the fact that the room descriptions are original, colourful and varied, puzzle-solving can get quite interesting.
Guilds give different bonuses and advantages, though, and joining one is usually a good idea.
When you reach a certain amount of points, you get a level. Points gan be gained by defeating difficult monsters, and sacrificing treasure. An interesting feature is that levels seem to count for less here than on other MUDs. Besides the fact that higher levels have somewhat more HPs, the only advantage they get comes from certain special abilities their guild gives them. Equipment, however, counts for a lot.
