Which home console games are unplayable on a handheld?

Any game that puts the 2nd analog stick to good use...but with that said I'm still not convinced handhelds need a 2nd stick, it seems Nintendo agrees by only putting one on the 3ds :D

Nintendo are going to use WSR Archery controls as the second analogue for 3DS in any game that requires aiming. It works well and is better than a second analogue.
