I finally decided to start up Mario Tennis Aces again to check the last update they did to the game. As expected, they have not fixed the biggest problems with the game menus and options available.
Besides the much needed gameplay balance, one of the things that Mario Tennis Aces really needs are new game options, specially when playing offline. Like I said in my Quick Review a while ago, the game barely has any content and it depends mostly on the replay value of its simple online multiplayer. And the little content that it has is quite complicated and confusing to configure the way you want. Sadly, the rushed updates clearly indicate that the game was released incomplete, similar to how it happened to Mario Tennis Ultra Smash.
