Do we know yet how much if any source code made it out? I did hear something last night about the full source of one of the older gens/games or something. This could prove really interesting, especially for the modding and reversing scene if a lot gets released.
Everything is out. We can theoretically make anything we want from Gen 3-5, that includes bringing back Dreamworld.
We haven't even scratched the surface, it will take years to see anything take effect. Hell, it will take weeks if not months just to comb thru everything and document it.
Not in games, but in the anime Dawn is 10
I mean, 2 extra years doesn't make it much better when you realize they took away her pants and made her wear an extremely short skirt because they knew this would sell more copies. Then Platinum came out and when they had a chance for a redesign, they gave her an autumn coat...with no pants. They knew.
For those who missed it, the original Dawn design:

But hey, at least they had some self restraint and actually made her skirt longer. That means we only occasionally get to see her butt(more often in the Japanese anime, as there was more "fanservice" there that was censored in the Western episodes).
I do find it interesting how indepth they go with the personalities of these characters, who mind you never speak or do anything in the story. How would I know that Lucas is into Linkin Park?(Patrician choice BTW) and how would that effect the games?
Imagine if there is a document for

aka the protagonists of Sun/Moon, an entire document wasted since you play as a plank of wood that occasionally throws a Pokeball around. Lily is the main protagonist of those games, after all.
