I think they should just chuck all the regions into one, maybe add a new region, and just make one awesome Pokemon game.
agreed. I suggest bringing back the added mystery gift bonuses from G/S/C. Like the basement battler in viridian and some of the . If you could set one of the people you've battled on wifi as the basement battler... man that would be awesome.
Overall, outside of wifi, the game has little replay value. If they added the features and extras from all the previous games into one, then they could take out wifi and still get the same amount of replay value.
I really want to see a combonation-region version, but I just can't see nintendo doing something like that. I'm still crossing my fingers though.
