So me and a couple of my friends are interested in buying the new Nintendo 3ds xl for MonHun Gen, but both of them are situated in Brunei right now. I've read the FAQ but some stuff i'm not too clear on...

1. From what I understand NA and Asian models are practically similar, only they come with different adapters and the Asian model is cheaper. This correct? Why the Asian one cheaper? Which is more widely sold?
2. Will I be able to play with my friends online when they're in Brunei? Has anyone tried this out? Any sort of problems encountered?
3. Also will we be able to play together if we have different models although playing the same version of game? (I.e one has NA model while the other has Asian model both playing NA version of game)

Sorry if some of these are dumb questions, just wanna confirm can actually play with friends before sinking RM1200+ on this...
thanks in advance the help and guidance

Thanks for the help! Rm1200+ is just a rough estimate, considering i'd be also be buying a game and an accessory or two. If they'd release a MonHun Gen special edition 3ds then I wouldn't mind bumping my budget up
