I love crunch, but to me it's secondary to how much the game mechanizes the creation and maintenance of narrative.A new version of RM has started to come out! It's pretty crunchy.
There's also HARP. And Against the Darkmaster.
And that's just in the RM-verse.
Torchbearer has a recent 2nd edition, and it's not exactly a low-crunch game!
