Lego games (particularly Lego Batman)Unfortunately, the sale fell through, so I'm still on the lookout for my daughter's Wii. Maybe I'll buy a retail unit, or a cheap one off e-bay with no games, and get the games later.
The deal (with all the games) sounded too good to be true. I smelt a rat. So I outlined exactly what I was expecting to receive for my money (based on what the seller had advertised), and insisted the seller provide their confirmation, prior to my PayPal payment.
The seller finally admitted the Wii, which they had advertised as PAL format, was actually an imported Japanese Wii (they had NOT disclosed this in the item description).
I've never heard of a PAL Japanese Wii.

That sounded dubious to me, so I sent them packing. The seller mentioned they're now going to offer this dud as a "second chance offer" to the next highest bidder.
Cheers.
