Well, after realizing that this game is being released this month in the states, I had to dig it :P
Mario Kart DS is going to be one of the first Nintendo DS games to support wireless internet gameplay with anyone around the world. This multiplayer twist to the series is accessible through wireless hotspots, WiFi routers, or Nintendo's own USB Wifi Conector that is to be released the same day as Mario Kart (Nov. 14).
Mario Kart DS will feature many new maps along with an assortment of karts to choose from that have also been added to the DS version. 50cc, 100cc, 150cc are still playable.
This will be one of the greatest handheld releases of all time ;)
I plan on purchasing this game on the release date, along with a WiFi router and/or WiFi adapter.
So, will you get a WiFi Adapter (Nintendo's) or a WiFi router if you don't have one?
