it's actually useful when trying to steady your aim. And there's a slew of games coming. Ghost squad is one of my arcade favs. I even got my mom to play it. So I'll defiantly pick that up. But games like metroid aren't really useful since you have to jump and use ther buttons. Link's crossbow training is a perfect fit.

As for ergonomic-ness, I've found when in a rail shooter situation, it's easy to hold the trigger with your dominant hand and hold the back like the front of a shotgun with the other. Very comfy. Of course if you have to use the stick, you're stuck in the standard position. Standing up really helps though.
