C64 and many Atari, Apple, and Nintendo products used it, including arcade machines. People still make new stuff, with new interesting hacks, for all of them, every day. I suspect anything new wouldn't be as interesting as playing with the old systems because if anything needed more interesting features these days, they'd use something much more modern. Back then they had to squeeze all the "interesting" they could out of the 6502 specifically. You can easily play with it in the browser [1].
