I've been playing Materia Magica (Moongate Online as it used to be known) since September 1996. As one of the older people on the game, I've seen people come, and people go. As with every game, there are some people who seem to insist that everybody but them is cheating, as well as getting upset with people in the game over some trivial matter, like being killed, and then doing something stupid, such as going online and writing a bad review for this game. ;)
I'll be one of the first people to tell you that Materia Magica is one of the most addicting games out there. Every character level one can get is supported with equipment, and knowledge about where to level and what to kill. With several new features destined to come out sometime in the next year, such as Archon Classes, and Clan Towneships, work on Materia Magica never stops.
Oh, Archons are the 'Avatars' of the game. The highest level possible. There are a total of 181 Archon levels to try and get.
Throughout all of its existance, Vassago, and his co-Admin Darkstar, have been in charge of MM/MG, and it's grown well under their care. I, personally, don't plan on leaving anytime soon, even after 6 and a half years. I encourage others to come and try it at once, for once is all that's needed before you're hooked by its immersive system.
