I got an idea about Zapdos, Moltres (or how u spell it) and Articuno, and the other good poke like magmar, lapras etc. should be hidden on the map. also eevee etc. (so u actually explore and when u found the hidden places u get so happy and when u catch it feels awesome xD)
but other pokes could be thru tp ^^ this would be awesome cause then low lvl will go fast while high lvl will be interesting and awesome xD
edit; also quests where u get pokeballs/ tms/ poke eggs like a togepi egg or something wud be so fkin awesum xD
