it's just wiiplay. it's a bunch of random games that introduce you to the wii remote. it's already out in japan/euro i believe. it's not nearly as good as wii sports.
Yeah I live in Australia and have had it since launch (came with extra controller) shootings alright, it's just like Duck Hunt really and Tanks is actually pretty fun but all the other games you probably won't play more than once.
See how the market is you might be able to pick up a copy on ebay or ebay your controller, I know enough people that would pay me retail for the controller if I didn't want it.
