Is it really necessary to charge the 3DS fully for the first time?
I know it sayss so in the manual and I know certain types of batteries have different charging needs... but I don't know if I can wait 3 hours to turn it on for the first time. XD
No, it shouldn't hurt anything since they are using Li-ion. I would suggest doing it simply so that you can have a full charge the first time you play it and maximize your play-time
