“Historically, license video games have been an excuse to rapidly churn out a shoddy product after cutting development corners in order to push a title onto the market that only profits because of its name, without nary a care given to the player experience. In 1990, legendary developer Capcom provided the gaming world with a wonderful exception to the trend when they produced Disney’s Chip ‘n Dale Rescue Rangers for the 8-bit Nintendo Entertainment System home console system.”

This is a fantastic (quite literally, since this game has many fans) example of a “pleasant surprise” NES title. You may have expected a crappy license game, a kiddy game, or a generally poor game, but this is an exceptional, solid, fun video game. Some of the gameplay mechanics were rather distinctive, and could take a little getting used to, but once you were hooked in, the distinctive experience is nearly unforgettable. Simply put: This is a good NES game. Read the full review for some insights into its unique place within the 8-bit pantheon in the context of time and other cartridges.
