The one way transfering/trading is probably the worst part of it all.
I think having a new world to explore and more pokemon to catch is worth giving up that small thing.
Now the better aspects still are the Wifi, Voice chat with friends, connectivity with people all over. Guaranteed to make sure you make a new friend everyday if not ever hour once you start worldwide battling.
The graphics, music...the whole package of pokemon on DS makes this franchise even more special.
