I can see one scenario where this price is justified.
Let's say you were a caveman, recently unfrozen. You then become a successful lawyer.
You currently haven't purchased any cellular phones, and you own no consoles. And for some reason your caveman mind is drawn to these colorful images representing birds colliding with structures. You want to play this game, and your current lawyer salary allows this.
A new iPhone 4 is $300 - a new 3DS is $150. Buying a 3DS and a copy of this at $40 would save you money if and only if that's all you wanted to do - play this game.
Other than that, yeah. Hard to beat free.
