It's not the categorization that interests me, it's the kind of cross-genre parallels. The general trope is what is far more entertaining to learn about than every single media item it has ever been in.
I don't often browse through the actual games, novels, etc.
But I can start by learning about different portrayals of psychic powers
, moving to Astral Projection, then end up on convenient coma, which lands me over on the Empty Shell.
It's not really any different from browsing through Wikipedia articles, except that these articles are limited to topics on media portrayals.
