After further thought, I guess I can agree. Of the official D&Ds, 4E is "most similar" but it's still far removed.
Sure, but if you tried using SC in place of combat you'd get rebellion.

That said, I think I remember someone coming up with a SC for a magical contest, but my 4E players didn't want to use it since, "magic is powers." So, again, I don't think it's that similar. That said, 4E is definitely the most "narrative" of them as far as mechanics baking the narrativism in. But Basic D&D feels closer, since the way we played it there was a lot of narrative action that was defined by player decisions without the weight of the mechanical systems that were added in later editions.
