Pathfinder 2e has a lot of 4e DNA in it, and I routinely see people treating significant swaths of it as if it's a video game. Which, as a PF2e GM and player, is bizarre to me. People talk about playing it as if they're just exposing the mechanics to the air.

But if I was going to make a video game, 4e/PF2e are absolutely what I'd base the mechanics around. They're pretty tight systems, mechanically.
