I don't want to buy it. Allow me to elaborate.
They completely left out those who didn't have a DS. If I were to buy BR right now, I couldn't completely enjoy it until I shelled out another 180$ JUST so I could use non-rented pokemon.
Ok, so the online may be ok, but once again, if you don't have a DS, you are LEFT OUT. You cannot communicate WHATSOEVER, whereas if you have a DS (Extra 130$) , you can VOICE-CHAT. Gee. That's a REAAAL expensive microphone. I have a 5$ one RIGHT here. - points to thing dangling from desk -
Sure, you can use the Wii controllers to control the game. That's one thing they didn't leave out.
What's the point of using your DS as a controller? Wow, a 130$ Wii Remote.
I may elaborate some more at a later point in time.
