Yup~ And, because it came after Platinum, it would probably include a Battle Frontier! ('cause the Battle Frontier idea came after LG/FR, probably)
I have to admit, I still like Emerald's Battle Frontier more than Platinum's. I mean, I love the Battle Arcade ROULETTE and the Battle Castle and the Battle Hall STAGE, but... I still love the Battle Pike, Dome, Pyramid, and Palace from Emerald.
Ah, the battles, eh? XD You on the first chapter or did you get further?
