To be honest nothing except maybe the game was too easy.

The Bottom Line
The best Mega Man in the entire nes set. The game has the perfect balance and is the longest Mega Man in NES history. The music in many cases is superb and there is many memorable moments to be had in Mega Man 3. The amount of improvements was vast compared to every other Mega Man game in the NES history and has innovated the most. Rush, Protoman, The revelation at the end of the game.....

In other words this is THE Pinnacle of The NES Mega Man series in my opinion. If you just love platform games with running, jumping and gunning then look no further then Mega Man 3!
