[HMM IV TOURNAMENT ON] New Year's Olympic-Heroic Games

On average, how long will one battle last?

So, there will be a battle right away in the first and second stages. Therefore, the battle time depends on how much time you spend on it (it can range from 5 minutes to an hour). As for the third stage... Considering that you have a modem, the game will take an average of 2 hours.
