1. Just want to know how the multiplayer works,does it connet to my wifi router along with my wii? and then just swap game codes and you can play online? can you play outside of your own region? (i.e. im in new zealand and none of my mates own a DS so could i play people from this forum in the US or UK?)
Answer: The DS will connect online using your wireless router and you will be required to swap friend codes to play online games together. You can play your friends from anywhere in the world. You can also play random people without friend codes in some games like MK online.
2. also want to know how decent the graphics and gameplay are, have played a PSP and was impressed (however last handheld i owned was a yellow pokemon edition gameboy,a good 6-7 years ago)
Answer: The graphics are more than decent. DS graphics are not superior to the PSP graphics but it has great graphics for its games. The game-play varies from game to game.
3. Also what games would you recomend?
Answer: I would recommend a few:
Mario Kart (online)
Animal Crossing (online)
Metriod Prime (online)
New Super Mario Bros
Hope that helps.
