I've been playing for over 3 years and there's never been a dull moment.. there's always something to do. While I'm not questing I'm killing outlaws that stalk pk rooms looking for a fight, in between I'm fitghting archon hunters left and right so I can gain more experience and level. This world is everchanging, there is a great set of imms working on the mud every minute of every day and night, constantly adding new areas with new items and adjusting the coding to make game more balanced and more enjoyable. This is the only game you'll ever want to play.
Also, when I entered the world of MM I had no RPG background, I'd played it all... first person shooters, 3d stradegy, adventure, etc. I still try to play many of the new games that come out... I've mastered Diablo, Diablo 2, Half-Life (and every mod) Quake 1-3, however I keep coming back here, I have more hours in this game than any other game I've ever played in my life.
Come, you will not be disappointed!
