I think I'm the odd one out - not just between us, but across the whole RPGing community - in ranking Prince Valiant above Pendragon. But I am (reasonably) serious about it.
And as I continue to cultivate my interest in Mythic Bastionland, I think the likelihood of me ever spending time with Pendragon gets smaller and smaller.
I don't know if you've ever read this from Edwards, comparing Pendragon and Wuthering Heights <
The Forge :: Wuthering Heights>:
It took me a bit to realize that the behavior-system is the same as the more familiar opposed-trait method from Pendragon, but I think that Wuthering Heights' version is more easily understood and more elegant, mathematically. Here's the idea.
Think of an opposed pair of behavioral categories, with a probabilistic range of numbers in between. Think of a "sliding toggle" that rates, based on its position, how much of the range on each side is represented or governed by each category. On each side, under each category, is a long list of possible player-character actions.
In Pendragon, you might have "Mercy" on one side and "Cruelty" on the other, each rated at 1-20, with the total always being 20. If you do something cruel or merciful, you receive a "check" on that side of the dichotomy, and between sessions, checks warrant a roll to see whether you lose a point on one side and gain a point on the other (as appropriate to the action). The more of the 20-point range you have on one side, the easier it is to keep racking it up.
In Wuthering Heights, it's the "toggle" that's named ("Rage") and numbered, not the sides, so you have one number to roll over or under on one range, not two to roll separately on interacting ranges. If you were to translate Rage in Wuthering Heights into Pendragon terms, you'd have Violence and Apathy on each side.
Aside from the frequency of instances (in WH, these rolls come a mile a minute), the math works out pretty much the same as in Pendragon and is easier for people to understand, based on the roll under-or-over thing method. And in WH, it is the ONLY resolution system for actions, not an add-on as in Pendragon and Unknown Armies.
Pendragon aficionados are familiar as well with the required "check," meaning that the GM may call for a test of one of the sides, the results of which dictate a response. This is equivalent in spirit to the Wuthering Heights effect of gaining/losing a lot, which also results in a required response. So we see a very similar mix of dice-dictated actions DERIVED from the scale, as well as player-voluntary actions that AFFECT the scale.
I think that the idea behind Wuthering Heights' resolution method should be developed and applied to a lot of RPGs, including those of more serious intent and content. It's tremendously easy to understand and apply, and it offers a good mix of "what the dice say" and player control. I see it as a perfect blend of Ghost Light (using the emotions AS the resolvers, letting the physical side of things simply reflect the emotional side) and Pendragon (shifting values and within-character conflicts, as reflected by time and events).
[In passing, I tip the hat to Call of Cthulhu, for introducing personality mechanics to role-playing games, and to Unknown Armies and Fading Suns, both of which provide methods evolved from Cthulhu and Pendragon. All of these represent a "family" of personality mechanics, which may be compared to the adjective-driven "family" begun by Champions and continued through most RPGs since then, like Vampire, L5R, and many others.]
