I think The lighting weather effect is to make pokemon paralyze, of course except for electric.
So a new weather condition? I'm wondering how it'll be executed. Now fingers crossed that the seasons feature from 5th Gen will be retained, because I loved how some parts of Unova had accessibility change based on the season, and I'd love to see how cool Deerling and Sawsbuck's forms look in the full 3D graphics. The seasons added a very "realistic" feel to 5th Gen so it'd be silly to not include them in this game.
No images, I just saw this information.
I'm also excited about this, the elite four would be challenging.
Yeah, it seems like Game Freak have learned their lesson from the weak levels the Gym Leaders and Elite Four were in 5th Gen. Maybe this was why they made the EXP Share now have functions similar to 1st Gen's EXP All.
