What I don't want:
~Two rivals, one with each starter (this really bugged me about DP, and I don't want it messing with HGSS. One rival, one starter)
~Honey trees (headbutt any day of the week)
~Battle Frontier (I know many people enjoy these, but I hate them- they are extremely boring and their only purpose is spamming with high IV/EV pokemon)
~removal of Kanto (Kanto was a big part of GSC, and removing it would make it too different than the originals)
~Contests (They kept them out of FRLG, for which I am grateful. Johto doesn't have them, Johto doesn't need them. If they do have contests, I hope they return to a more RSE-like contest format- the format in DP is so much more annoying than the RSE format.)
