I guess it should first be said that this game rocks. it is highly story oriented in its game play, and although I suppose one could manage to do a nice dungeon crawl campaign, the open world and highly customizable characters beg for something more. It is not the easiest game to run as a gm, as much of the open nature of the system falls on gm shoulders, but it is by all means not hard. It just calls for actual storytelling skills, and actually opens up many doors for the gm, as literally anything is possible, in ways that allot of other games that say the same thing cannot reproduce.
The two greatest things worth mentioning are the character customizability and the game system itself.
When I was told that the game featured a d-2 system, I thought it was not worth looking at. I mean, flipping coins? What is that, pokemon? DO NOT MAKE THE SAME MISTAKE! the d-2 system in MLX is modified in a sort of white-wolf manner that is very easy to pick up and works wonderfully, allowing for, and sometimes forcing, actually strategy and thought in a roll(hereby called flip, because it is better), which just doesn't happen in most other rpg's. If you are like me, and are tired of all the d-20 mess in modern rpg's, defiantly check this game out. It is a refreshing change of pace in an overly stale gaming market.
As for character customizability, that is really what the whole game is about. There are about 100 pages of perks, which function allot like perks from fallout or feats from dnd, and are broken up into about as many perk trees. Add to that the fact that each perk can be taken up to three times and that all perks (except for racial perks and the odd but fitting religious perks) are open to everyone, and you have a game where characters will never be like any other character in a party. Some are horribly broken while others are almost just for taste and flavor, but everything has its counter, its weakness, and its arch-enemy, to which it will fall. The game is, despite all the craziness, very well balanced, which is something you will not believe if you happen to just read the manual. Once you start playing, though, it all works out almost magically.
This is one game that I think everyone should have in their bookcases, especially those bookcases too filled up with rpgs that promise the same old adventure. MLX is truly something new, and will deliver nothing but hours upon hours of crazy addictive fun.
