Sadly I think Rayman will be the first one to drop in price (and be the cheapest)... but I also think it's the better game of the 3.
I love WW, my favorite 3D Zelda, but that bloom...Just watching the title screens side by side,
makes me want the option to toggle it off. Between the new clouds and vaseline filter, it totally un-improves the art direction in my eyes (I'll give them the shadows, those are awesome). Plus it's a 10 year old game that's being sold for $50... I'll stick to the original for now.
Poor Pikmin. Unloved. Unwanted.
