Though it may not yet include all of September, Kotaku's monthly monitoring of the most played Wii titles still provides some interesting insights. For one, it seems that Super Smash Bros. Brawl is the best bang for your gaming buck, as users are STILL sinking an average of 71 minutes into the game monthly. We're surprised to see Wii Sports Resort's absence (thought it was perhaps hampered by the lack of September's second half), but we're even more intrigued to learn that Rune Factory: Frontier is apparently way more engrossing than we could have ever imagined.
