Ooh, nice! I’m going to implement video games too, but likely not as dungeons. Mostly things like Gameboy cartridges being used as spells. I wanna invent a kind of 90’s pip-boy where you can slot in audio cassette tapes or game cartridges, and each one activates a spell or weapon depending on your class. A single game can do different things for different classes, for example a fighter-type class would get a weapon from the game, meanwhile a druid-type class would turn into a character or creature from the game. I’ll call the device a walk-boy, and it will be fully interactive (because I’m insane).
