Yeah, White Wolf mechanics tend towards the awful.
As an Exalted fan, I've seen some of their worst work up close.
PS: Giving strict prereqs to ACaEBG is really just a band-aid. It makes it harder to use the power with the things that break it, but it doesn't really solve the issue. To do that, you need to make it incompatible with a number of other things.
I almost worked for them as an intern in Georgia. Then they announced they were ending their universe at Gen Con.
i opted out a that point.
Point is I own most of their books. Yeah lots of their stuff needed some mechanics work.
I'd personally put the White God on equal footing with whatever makes up the top of the Outsider pyramid, above their Walkers. They probably outnumber Him, so keeping them on the other side of the Gate is really, really important. This is my personal canon, but it makes sense to me - putting the White God above even the Outsiders is too close to omnipotence. Once the players start asking why the White God doesn't step in and fix X, he becomes Elminster and it breaks versimilitude.
As for the tangential arguments: arguing for narrative balance is a functional argument in a system that supports it. DFRPG, which specifically encourages players to build their own Stunts and Powers and spell rotes and such from existing mechanics, is not such a system. Narrative balance is 0-weight because you are straight-up told "mess with it and make it yours", and so an argument that All Creatures are Equal is limited by narrative is absolutely nonfunctional.
What it is ACTUALLY limited by is "one Fate Point". What a Sword is limited by is "a context approximately as restrictive as a Sword's agenda" but that's already an inherent trait of IoPs and doesn't cross over to All Creatures are Equal. If there is a balance problem here, it needs to be addressed, because Dresden is not a locked setting where only Knights can have such a power, it is an open toolkit by design. It goes against the grain of DFRPG to assume that anything is limited to its original context. It goes against the RPG itself, which is 100% sufficient, but also against the Dresdenverse setting, which is a narrative kitchen sink with very few absolutes in the first place.
Well, you guys win. Perhaps win is the wrong word. I already said that by system all powers can be reskinned. I knew that. I just disagree with it and don't care for it. I'll just have to shut my trap and live in my safe, secure, balanced, house ruled setting. I accept this. Think I'll hide in my bunker now
EDIT: One thing to point out first:
I know Sanctaphrax and I agree that ACAEBG should not be stacked on Evocation.However, this is allowed by cannon rules when any power can be reskinned and ported to anything else.
-6 to 8 (cost is immaterial at this point -12) Sponsored Reaping MagicLike Death Himself, Fourth Horseman of the Apocalypse, you would reap God were it His time. (Supernatural referrence) With this power you surely could. By spending a Fate Point or the equivalent thereof, you may satisfy any or all Catches with your evocations or Thaumaturgy spells. This effect functions the same as ACAEBG and TCATWEGMD.
Now of course, you can still get your discounts for Evocation or Thaumaturgy. Coming up with a concept to use this is pretty easy. It is totally legal by RAW, save a bit of nitpicking and adding some fluff; it is even ready for our Custom Sponsored Magic thread.
This just leads to infinite escalation. -3 power "The Catch and Nothing but the Catch" has already been created here to ignore ACAEBG.
Well I want a power called:
-??? "There Comes a Time When Even Gods Must Die" - that is a Lex Luthor quote btw. I have your catch even if you have that paltry, silly power known as "The Catch and Nothing but hte Catch." Also mine has a cooler and longer name so it trumps yours...
My heart is all twitterpated just thinking about it!
