Rayman Origins for the home consoles (360/PS3) retailed for $60 when it first came out. So it makes sense for the Vita version to be $40. If you can't bother to pay full price, then wait a month or so for the price to drop then.
Just wait 6 months on Vita. It looks like a very nice system but everything associated with it is insanely overpriced. I am a huge early adopter but this is one time I'm on the sidelines waiting for drops. Especially since they're already trying to pass of mobile games (Dungeon Hunter or whatever it's called) as a $40 game when it costs $1 elsewhere. Yeah, yeah, the Vita has analog sticks...not worth a 4000% markup. Rayman should've launched at $20. Wake me up in a year when Resistance is out (hey, a FPS for a device that was supposedly redesigned to cater to the FPS gamer, what a concept!), Motorstorm and ALL these overpriced games are $10-$15 used somewhere.
