wow ok so no one's gonna bring up altwfc or wiimmfi? alright guess i'll have to be that guy. ahem...
you can use altwfc or wiimmfi to play city folk and a buncha other wii and ds games online on an alternate server. since we're not allowed to discuss how to install either one since it's basically hacking, you're gonna have to look into it yourself. i personally prefer wiimmfi btw.
staff on this site need to chill out.
