Fun Fact #56 - Chex Quest, which was based on the Doom game engine, is a non-violent first-person shooter released in 1996 as a Chex cereal promotion. It's the first video game ever included as a cereal box prize. The very first video game (and video game character) ever to get its own cereal? Donkey Kong. The Cap’n Crunch-like cereal was “barrels of fun for breakfast,” and not surprisingly the cereal itself was shaped like tiny barrels.
