Voltorb Flip is soooo frustrating but so addicting at the same time. Why Nintendo, WHY!?
Also, TMs in the Game Corner are ridiculously overpriced compared to the Pokemon(though this has always been an issue since like Red and Green).
Another problem I have is the fact that the Battle Frontier is identical to Platinum's. I realize this was to keep compatibility with Platinum's, but we could've at least had different Frontier Brains.
Also, some of the GB Player songs are off. I know they're made from scratch and not directly ripped from G/S, but when I play the game with them on, it makes my ears bleed when I hear the Johto Wild Battle theme. Ugh...the intro to it...
