As an amateur tech nerd who stumbled into these posts via Numberphile: It's no surprise that Uma Musume crept in there, it's hugely popular. A bestselling mobile game, though the game itself is afaik only available in Japanese. (Why that particular weird token? No idea, I'm only peripherally familiar with the franchise.) Puzzle & Dragons is also a very longstanding popular game, so there's likely lots of discussion about it. Especially in "gacha" games like P&D and Uma Musume (where you obtain game pieces via essentially a slot machine), you often see that "awakening" phrase to refer to some kind of obtainable upgrade to a character or other game piece.
Oh, and Steve is the name of the default character appearance in Minecraft, so that's probably the association with Forge.
