I also would like the ability to cloud save. I'd like to take the game everywhere and don't want to start over or if people are sharing a pc, they wont have to be subjected picking save files. It should be a login but I guess that will hinder offline play...
Secret base, gts, wonder trade, flat battle, idk if this is already in game but accessories to put on your pokemon, like hats and scarves that show in overworld and battle sprites as well as clothing for us.
