Interesting question, ne?
I’m making this stuff up as I go, but I think you get a sense of what we are dealing with: how do we split these up in a meaningful way? I think Play is a fine description. I nest that under Discover, since in order to understand a game, to catalog it, it should be played (or attempted).
FYI everyone, if I move on What is a game page? I’ll be able to crunch through quests a lot faster! And I’m getting there, but real life stuff.
