I would want a new type(soul)
new eeveloutions
LARGE region
and something new like a training mode where you can teach your pokemon new moves and upgrade on the old ones(like does more damage or highr pp)
When they came out with the pre release pics, since it basically showed a dude in a cave, i thought it was going to be a diffrent type of starters. Like diffrent elements. But i was wrong. I kinda want like a dark,fighting,phsyic thing. Anybody else got any ideas?
