Just as examples:

• I’ve never played a Pokemon game despite being just the right age where my peers were really into gen 1 as a kid.
• I have yet to watch any of the Alien or Predator franchise movies (except Prometheus, which I didn’t realize was in the Alien franchise when I watched it long ago) but am planning on rectifying that when I can get a chance.
• Oh, and I’ve never seen the “hawk tuah” video.
