I don't rememeber Red Steel having this.
A "sticky aiming" function would only make things harder... I mean that's one of the reason dual analog auto aiming blows.
Someimes when you wanna hit the rocket launching alien you accidently end up stuck on the grunt.
You don't remember this because it was an option that had to be turned on. It made teh game really bad and much mnore difficult to control.
It was an option SSJ12 and as far as I know the only game that had it. It is not there to compensate for poor controls but rather to help people with shakier hands.
