Mega Man 5 is not as uncommon as some other NES games, but it might be tough to locate in its original packaging, especially in good condition. The popularity of the game, paired with its scarcity, has increased its value among collectors. One reason for the game's success is that it is widely recognized as one of the best entries in the Mega Man series, with many fans thinking it to be one of the best games on the NES. Mega Man 5 also brought various new aspects to the series, such as the ability to charge up your special weapons and a new companion character named Beat.
