From the RPG description here on RPGGeek:
A game too warped for White Wolf. A system too overpowered for Munchkin. A world too fraught with cliches for D&D. And it all rests on the classic twist in fate: the coin flip. MLX parodies classic RPGs and takes roleplaying into a new, more portable age, utilizing only the contents of a wallet for its mechanics. It is a lively and humorous system that draws on countless pop-culture sources for entertainment. This is the RPG that Jack Chick warned you about.*
This game contains strong language that is not suitable for all readers. Several may find parts of it in bad taste. MLX is also new and different, which many people equate with frightening or dangerous.
