But more than that... he changed quite a few things. For example, he made farfetch'd a bit stronger (like 100 att, and 95 speed... same defenses), serperior is now Grass Dragon, Emboar is Fire Dark, Samurott is now water fighting. Most things have their dream world abilities, or just new ones that kinda fit (for example, magneton has levitate now, chatot has adaptability, victreebell has intimidate etc. Plus random things get new moves like blastoise gets shell smash, and ampharos gets tail glow... U get the other starters through shaking grass as well.
Its quite well thought out... although the gyms are now amazingly hard... The first gym has 6 guys >.>... which consists of the 5 starters of their type, and panpour/sage/sear of the respective type.
