I will be playing the following games.
Arkanoid
Tempest
I believe those two games use very different spinners. The Arkanoid one has gears and has a slower/heavier feel IIRC.
The Vortex will be perfect for Tempest, since it is based on the original arcade spinner. It will work with Arkanoid fine too, although will probably not have such an authentic feel.
I don't have the Vortex, but having had 3 Oscar spinners (Model 1, Pro & Op/Down), I'm sure you would not be disappointed
