I wouldn't mind this if they only changed two things:
1. For the love of God, speed up the battles. I'd say roughly 80% of the battles in the game was waiting for your turn, and each battle dragged on for at least five minutes minimum.
2. The ability to just teleport to towns completely ruined the adventure aspect of the game. Honestly, create paths to the towns, make us able to catch wild pokemon in the grass the way Tajiri intended; and give our character the common sense to ride his scooter in towns.
I'm being serious when I say that those two problems stopped this game from being decent, from what I recall I had to tolerate the entire game; there was not one instance where I had fun. I'm personally ashamed that I wasted time I'll never get back into this game, I guess it was worth it in the end getting Ho-Oh and destroying my friends in Ruby. Upon them telling me how cheap I was for using him, I only responded with, "Once you've played the entirety of Pokemon Colosseum, then you can talk to me about fair."
