I think the issue you’re having is that you’re treating them as categories and subcategories, like most things it’s never that clean. It makes much more sense if you treat them as unordered tags. Arcade isn’t a subcategory of tennis.
Say for instance you had a multiplayer racing simulator game, you could categorise that as multiplayer > racing > sim, but if you have a similar singleplayer game you have single player > racing > sim so clearly those aren’t just subcategories of single/multiplayer.
You could try sim > racing > multiplayer, but what about your city building sims? Now it’s your middle category that didn’t work right.
If they’re independent tags sim, racing, multiplayer you can change any one of them independently. If any one tag changes that changes how the game is played.
