Any RPG with a good party system like Earthbound or Live A Live. Also other games like Pokemon and Minecraft.
Reading fantasy books and Brandon Sanderson (who is a genre all his own). I also LOVE DnD. Can't really put them all here because I'd be changing it every other day.
Whenever anyone publicly references something they know only two or three other people will understand it's like Plato's Cave; I can't see the objects themselves (the thing being referenced) but I can see the shadows on the wall (the reference itself).
