(inspired by Doom's pokemon battle music post in the VG Music thread)
Cyrus is a nutty bastard, and his battle theme is great.
D/P/Pt is probably one of the neater stories of the Pokemon franchise.
Part of the problem with Pokemon is there's not much to expand to anymore. I mean, you've got Mew, who contains the DNA of all Pokemon, then Arceus, said to be the genesis of all Pokemon. Celebi, the Pokemon of Time, and then Dialga, the Lord of Time.
There's a good story to be had in this world, Nintendo just needs to figure it out. They TRIED with the Gamecube games, but fell far short of the mark. The story still boils down to "Criminal Organization exploiting Pokemon to nefarious ends! Oh and also BE THE BEST IN THIS REGION". I'm kind of looking forward to see what they do with Heart Gold and Soul Silver, the Gold/Silver remakes, as there's a lot of potential there.
