Series creator Masahiro Sakurai offered a new perspective this week in his column in Weekly Famitsu. Being on the developer's side, Sakurai is able to view online player statistics for the game, and one particular statistic was brought up. "For Super Smash Bros. Brawl, the individual character win ratios lined up nicely in a staircase format, but [for Super Smash Bros. for Nintendo 3DS] one fighter has a significantly low ratio." Sakurai wrote. "It's Little Mac."
"Little Mac is a fighter with very pronounced strengths and weaknesses. While he has an enhanced dodge and megaton-level punch for aggressive play, he has very weak jump power and a simple back throw along with a follow-up attack prove to be crippling."
Sakurai notes that players may perceive Little Mac to be stronger than he actually is, which has led to the influx of online usage of the character. "It appears that the biggest reason for his low win ratio is because people fall under the assumption that 'Little Mac is strong!' and all rush to use him only to get pummeled in return." Sakurai remarked. "He gives the impression of being able to win easier than other fighters which leads to more people using him, but in reality, he's a difficult character to actually continuously win with."
For Sakurai, the player-perceived imbalance is actually an ideal situation for greater game balance. Having players flock to use one character will teach other players to counter that character and encourage higher levels of gameplay hence Little Mac's low win ratio.
