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.
Not quite what you are asking, but the first time I saw the video from 9-11 of a plane crashing into a building was around 2014-2015 when I moved to NYC. The people I was working with there couldn’t seem to believe that I had never seen it.
