I always found silly that 4 houses can be considered a town, and the cities are equally small :/ The only one I consider a city is Castelia. --- (...D-Do I really inspire this sort of frothing desire from the female masses?)
All I care about is them improving the cut scenes introduced in gen 5.
I want to see an introduction with Yveltal where he lands and crushes a swarm of pokemon with a single swipe and flatten land. Then have Xerneas step out and all the trees that were just flattened by Yveltal start to regrow and sprout up.
These two beings standing face to face. http://gengame.net/wp-content/uploads/2013/01/Yveltal-styled.jpg
