In the first post it says that there will still be SEVII isles but that little bit of hoenn that you visit in this hack is supposed to overwrite the sevii isles or both Hoenn and sevii will be included ?
Despite the fact that i voted no ( bad dude
) i would like to see some pokemon like jigglypuf or jynx or raticate be replaced by genIV and genV legendaries..but if you do consider adding gevIV genV pokemon don't ( please don't) overwrite 3d gen pokemon....
Also if this will have 386 pokemon catchable you would have to add events for some pokemon like groudon or kyogre..
