If you're into VSRG's, I'd recommend OutFox (New StepMania), osu!mania, Etterna (Keyboard StepMania) or Quaver. If not, then I play osu! std. (Standard).
They're definitely challenging lol. I think the closest thing I to a VSRG was guitar hero and DDR. I was ok at guitar hero, not so much at DDR though.
DDR is a VSRG, but with feet essentially. GH is more of a different class of rhythm game as far as I know
One things for sure, my hand eye speed needs a lot of work lol. I was trying out Etternia and learned the hard way.
