Well... Why?
I've had some success making mock of this style for my own games, but the benefit comes more from understanding the structures and the reasons for their existence than from direct copying. For a 3.X game, Wyre establishes and enforces certai assumptions about what things mean that are different from standard, and it's the unequivocal player buy in which makes it work. Wizards being scholars who devote their lives rather than just being a class of people who happen to own reality. Outsiders who matter. Gods and powers which present more than X hit dice outsider when you think about them – that's a big one, it's very hard to generate proper reverence or respect for these guys in most games. The historic bases with game world and game rule touches are what make this so fantastic; the nobles of a fallen land joi
Joining a vampiric prefigure, the enormous cost in horseflesh to maintain griffon cavalry, the barbarian army building a brewery because without beer, what is war? The feedback loop wherein dramatic and interesting story progressions create a natural progression of mechanics using templates and class stacking. These are more important than any actual rule or mechanic sepulchrave has given us. These are the weight of a world that functions and runs. These create texture.
That texture is more valuable than the rules which, for one man and one group with specific focus and certain traits that likely will never compile again, created that texture. =)
Why? For convenience! I don't want to run Sep's campaign (although I sure wish I'd been playing it). It would just be neat to be able to read through the Story Hour thread and have the rules posts he made neatly arranged with the corresponding spot in the story. For example, Eadric has dealings with Soneillon in the story and she mentions something cool like the ecstasy of negation. Are there stats for that? I can't remember. If someone collated the SH and the stats, I could look at the most contemporaneous stats for Soneillon and see if there's a write up. Newsletter. I'd subscribe.
