I Personally think an all characters speedrun in each cup should be added. To explain better I think that you should have to play through the mushroom cup with all characters in a row. The splits could consist of the time you get with each character while playing that respective cup. This could work for the three different cups you play in versus Cpu’s Just a new idea for a new Mario Tennis Aces Speedrun category

New characters will be added in the next couple of months, and imo that would make your idea more complicated to be realized.

Just an idea if it doesn’t go through oh well

New characters are coming soon, and i dont think nintendo is gonna stop at september.
