FATAL is, somehow, simultaneously a masterclass in realism for the sake of realism, and also the most unrealistic game ever made. There is a specific stat for how many words per minute you can speak, a stat for the longest word you know, and a stat for how far back your earliest memory is. But also, the system uses the concept of "humors" as something that actually has real-world effects, has the aforementioned critical system where you can crit individual organs but leave the surrounding organs unscathed, the ability to roll up a 4 year old with B-cups, and all kinds of other absolutely deranged nonsense that has no business whatsoever calling itself realistic.

Oh, and if your character's intelligence is low enough, you get to roll to see if they have "R****d Strength". So that's great.

The one thing FATAL has going for it is how terrible it is. Any improvement would make it not so perfectly horrible, and thus not as good.
