Weirdly enough, there’s been A FEW of these types of games that were based either on a specific product or a specific brand, and they were for the most part, weirdly well done for the times they released in and actually sorta fun.

Off the top of my head, Pepsiman for a specific product and the whole lot of Lego games if we’re talking about a whole product line.

I think that whole genre is called advergames

Hell, 7up had a platformer. Wasn't a bad game

The best game that was just an advertisement was Chex Quest. But, I mean, they hired some teenagers who loved Doom to make the game and gave them little to no oversight other than "explain what a healthy breakfast is and include Chex cereal." So they just made a kick-ass Doom clone that only marginally advertises the cereal.

The packaging for the game really tried to hide it was an advertisement game. Title is Darkened Skye which says nothing about it being a skittles game.

Apparently the singular of skittles is "Skittles" according to that game

Unfortunately, Andrew Wilson needs more money to purchase more kidnapped children from Asia.

Cool Spot was my jam but I still drank Sprite
