just tried to play south park studios' south park pinball and found out...it wouldn't load. Apparently the Shockwave plug has not been ported over to Intel...yet...
Yes, it's been "ported over" to Intel for a while now. Version 10.0.0d26 is the current (just updated yesterday, I believe) model.
Looking at the South Park game, it appears that the problem isn't really Shockwave, it's an antiquated "Macromedia (now Shockwave) Director" plug-in that's the problem. To the best of my knowledge, there's nothing for it on an Intel Mac at present.
