In years gone by ive frittered away thousands of hours on this highly addictive mud.
Within the game players usually join a guild or clan. These vary quite distinctly allowing a wide range of variation in characters.
The coding quality is top notch, rooms are well described, quests well thought out and i can honestly say its the most bug-free mud ive played.
For people new to muds there is a very good online set of help files with extensive maps and players are generally very friendly indeed.
For the more experienced players there are some very tough challenges indeed, though the rewards are high.
So, in summary id say that if your looking for a friendly, stable mud with good quests and areas Midnight Sun is well worth a look.
