That sucks. Nintendo pretty much standardized their pricing in Gen 7 making all new DS games $35 and all new Wii games $50. I thought that was really cool, but I guess it was like a USA only thing or something.
Yeah, I think that was US only (like how retailers can decide for themselves how much the WiiU costs in Europe vs. the given price in the US).
Then again, I just bought three PC games for half of a new DS game, I'm not really complaining
