A modified Wii can now play non-original games as well as the original. Non-original meaning those downloaded from the Net and burned to a DVD disc. You can see those in every "
gaming" store in Greenhills.
UNmodified Wii is the one that can only play original Nintendo Wii games. No one has opened the Wii and tinkered with its insides.
I don't really recommend modifying a Wii since it updates itself when connected to the Net and future Wii games will require a higher version of your Wii software. There are some cases where a modified Wii stopped working normally when attempting to download from the Net.
I still recommend Celtex when buying your Nintendo Wii (
and DS) items. They're in the Theater Mall Greenhills. I'm not an affiliate or employee of their establishment but they haven't disappointed me in terms of the items I've acquired from them for 2 years now.

I say, keep it unmodded. Only buy games which you
REALLY like. Yeah, modifying can make you play
any game for less price but it's not worth it when you have a favorite game you wanna play then the Wii just crashed on you coz of the modifications made to it.
