Yup, the C64 still has a scene. Both of nostalgics enjoying old games, and of people making (and selling!) new games for it.
There are also communities for making C64 piel art and -- get this -- art doing entirely in PETSCII (sort of like ASCII art, but PETSCII has a more interesting set to work with).
What does "older men" mean? Bunch of people got their start in computing with Commodore 64s in the early 80s yes, but also mid 80s, late 80s, early 90s and even mid 90s. So people who were kids in the mid 90s also fall into this group, and I don't think they are old.
