You can use "Navi" to direct Z-targeting too actually (though you don't really need to).  And the Wii version is the only one with widescreen support, plus some of the minigames (like the Panzer Dragoon-ish section) are easily better with motion controls.

Really, mindlessly button mashing versus mindlessly waggling seemed like a non-issue to me.

The only actual reason is my budget being stretched thin. VERY thin.

UHmm not very likely :(

Piracy is huge here. I'll be hard to find someone with legit copies.

*Looking what consoles the people who wrote here have... Now translating the real meaning*

"Because I'm a Sony fanboy and Nintendo is Sony's sworn enemy and I'll not support it to help Sony. If Sony made the Wii, then I would certainly buy it."

I can't find 5 games I want on the system.

not enough games that interest me, the ones i thought i'd want i tried out and hated the controls.
besides there already too many games i want to get for my current systems
