hurm,

Considering you'll need a Wii Fit Plus and Balance Board as a start for Aerobics, that should be RM 350.

Mario games and dancing games can range from RM 120 to RM 180.

But what other sort of accessories do u need?

You may want to read the wii faq thread at the sticky area above. That should give you an inkling. If there's any other problems, feel free to ask me. Thanks.

Regions really. Games are region locked. So US games plays on US consoles. Vice versa with Koreans. However, Korean Wiis in Malaysia tend to be modified, hence earning the name transvestites.
