still, Nintendo is saying the WiFi connection of FREE, so no costs, asside from hardware.

to simplify...

Nintendo WiFi...

costs... DS price + game price = answer depending on location and game age.

WiFi connection after paying for game and device purchase = NOTHING.

WiFi connection limit = GLOBAL.

you wanna play someone from Japan, go for it, you wanna play your fourth cousin in Africa go for it, you wanna play your girlfriend and her friends in London then go for it! all while from the comfort of your home, sitting local to your WiFi connection. WiFi is connected easy through the air, and since all you pay is for the device used to play on WiFi(the evolved version of wireless connection, instead of being local, the span is near endless), the connection cost is NOTHING.

Nintendo is making the internet connection FREE for WiFi use, as other companies like Sony and Microsoft are making you pay to stay connected through all internet connections. wired and WiFi.

my cash is gonna go to Nintendo, as soon as I can get a Revolution to get my WiFi connection, then I'll be able to play anyone in the next Smash bros. ^_^
