The last time I checked, I was close to 130 hours. If my DS lite was compatible with WPA, then it would probably be higher.
I might buy a 3DS eventually, but if not, I won't be using Wifi any time soon.
Moving this to Pokemon Black and White Discussion.
To answer the topic at hand... I believe I'm on around 161 hours for White. Not played the game as often has I would have liked due to my job offline and preparing for the vacation I have recently returned from.
