As mentioned there will be few, if any, games designed solely for the A10 but there will be some which specifically take advantage of some of the new power. Though those are few at the moment.
But the good thing with iOS is it's linearity, with each new revision older games which weren't specifically designed for the new hardware also benefit from a boost. So some games that were less than optimal on older hardware become much improved. Even some that were good to begin with benefit from smoother gameplay with higher frame rates.
So, all of that needless waffle aside, here's some awfy bonny games to give a go. (In no particular order)
Unkilled
Asphalt8
Real Racing 3
Breakneck
AG Drive
Reckless Racing 3
Infinity Blade III
Oceanhorn
Dead Effect 2
Assassin’s Creed Identity
Need For Speed: Most Wanted
Riptide GP Renegade
Geometry Wars 3
Wurds
That's about it off the top of my head. Oh and the last one is a complete and total lie, it's one of my freebies, though the spinning globe of words is kinda nice
