Not sure I’d pay $150 for this obscure Wii game

I compiled a list of the 15 rarest and most expensive Wii games and what makes them so hard to find. Many of them have been discontinued or the publishers have closed.  The most expensive game, One Piece Unlimited Adventure, sells for $150 brand new.

Like I said before, Metroid Prime Trilogy is a want for me. Also, I’m surprised my dusty copy of Walk it Out is fetching so much these days on the second hand market. What about you: Any games on that list you have or like to get?
