I'm a bit of a completionist, so I like to scan the obstacles and try to pinpoint where the items are that I need to get. I always intend on battling every trainer on the route, so I plan out my path before doing anything.
It annoyed me so much in BW when I couldn't get items because it was the wrong season. Don't get me wrong, I love the seasonal differences, but it just killed me to see an item just barely out of reach and knowing that I couldn't get it right away. --- The Official Bulbasaur of Pokemon X's board Bowser Jr, T Zelda, Ridley, Palutena, Pittoo, Isaac, Shulk, Mewtwo, Robin, Balloon Fight, Crono, Mii, Megaman, Neku
