What part of the game is "crunchy"?
The characters are mostly defined by 5 fairly loosely defined "rings" and you can pretty much apply whichever you want to any roll in the whole game. There are also a set of skills that are a bit more narrowly defined (honestly, some of them might be too narrowly defined while others are too broad, but that happens every time someone comes up with a list of skills) but they aren't nearly so important.
The advantages and disadvantages and when they come into play are all crazy vaguely defined, pretty much whenever people remember them and can find an excuse and all function pretty much the same.
Mental damage is tracked, but when, where and how characters react when "broken" is entirely up to them.
NPCs stat blocks entirely consist of only 2 numbers.
The only part that has like... any crunch is the school techniques, something I feel they were compelled to include to make the clans feel different.
I don't know that I have ever seen a serious RPG system ever be put out that had less "crunch". Maybe Apocalypse World/Dungeon World could be a bit of a contender.
But-- man-- you ought to have seen the previous iterations of L5R RPG. 2 stats for every ring, some of which dictated numbers across the whole sheet, every skill tied to a particular attribute and all of them having different "roll this many D10s, keep however many and reroll if you get a 10 and maybe also add this number" and all to make a TN (good luck figuring out your chance to make any given TN without serious practice or a cheat sheet) and you had the option of making your number harder intentionally and only if you previously chose to do so did it really matter if you rolled amazingly high on half the rolls in the game, so only the other half could there ever be any surprise great successes out of no where. Also, every school had 5 levels with completely unique techniques that altered various rules and while the first schools made got to be neat and straight-forward, by the 20th school made they were really doing some convoluted things in order to arrive at a similar result as those earliest designed schools.
Seriously, other people are complaining that this RPG doesn't have nearly enough detail and significance to any of the number.
