Quoted from Wade:From my perspective, the extras on the Premiums and LE's aren't worth it. To other people, it's worth it. It's extra flash that doesn't fundamentally affect the game, in some cases I think it even takes away from the game.
LEs are about bling, no dispute there. However, this statement is generally wrong if we're talking about premiums. Specifially for Foo Fighters, there's a pretty large difference.
At least one Foo Pro/Premium difference ABSOLUTELY affects gameplay. On the Pro, Area51 multiball is a freebie, a gimme, no skill required - hit the right ramp over and over. On the Premium you have to finish the upper targets, loop the mini playfield on the inside shot a number of times, until a diverter pops up revealing a secret target that you have to loop to the outside of the mini playfield to hit, starting the multiball. That's a SUBSTANTIAL difference in gameplay that definitely affects the gameplay in a fundamental way.
Iron Maiden Pro/Premium is similar. The Pro mummy shot is a gimme (much easier) shot on an open playfield to the captive ball next to the center ramp. On the Premium, you have to shoot through the pop bumpers up the left ramp to lock the ball in the mummy. Premium requires more consistent skill.
