I think that, no matter how hard they try, Gamefreak will never be able to come up with a plot better than Emerald. It was perfect. I mean, sure, battling Team Rocket is always fun and Team Plasma's quest for world domination is exciting and all. But the only story that's ever really catured me is two rival enviromentalist parties fighting for what they believe is best for the environment. And i love that with the help of Steven and Wallace you can show them the error of their ways and they make good. So ever since Gen III I've been waiting for a better story but I'm stating to get a bit skeptical.
