1. I think my head (along with my wallet) will explode once I finally get myself a 3DS.

2. Just look around this subforum. Popular games are the one most people here talk about.

3. If you insist on physical shops. There're plenty reputable shops around 1Utama/ e@curve. Asia Games Channel and Gamer's Hideout just to name a few.

Finally if you have any more questions about purchasing 3DS. Please use the main 3DS thread as stated by Kenjixx.
