With so much entertainment to be offered in so many ways, some of the few downsides would only come in personal preference. Any seriously competitive fighting fan may feel left out on the grounds - the game never promises or delivers on a thousand different combos or miniscule timing windows, but that doesn't suggest a lack of depth within the game. Anybody not as interested in the extended "rehashes" of old Nintendo themes in a compilation may fail to be charmed by the game's material, but that doesn't mean the game missed entertaining allure. Any graphics whore will mock the visuals and say "not next gen for me", but that doesn't mean the game isn't beautiful on the Wii. Aside from the ironic nature of premium quality in single player, the game is a step up in every way from Melee, and will remain as one of the year's best in terms of lasting appeal, and the single most potent advocate to buy a Wii.
