In prototype versions of McDonald's Treasure Land Adventure, the shops were McDonald's restaurants, and all the meters and power-ups in the game were McDonald's products. McDonald's burgers as health items in a game could be seen as endorsing them as a healthy food, so it was likely changed for the final game to avoid this perception, and while at the time Ronald McDonald was still seen holding or eating McDonald's in advertising, in later years he would be mandated against doing either. Additionally, a developer from the game has claimed that McDonald's were opposed to the collectibles because they didn't want hamburgers being left on the ground.
