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

Okay, but approximately how long will it take?

It all depends on how the game progresses for all the other players. The first stage will be quick, the second will be slower, and the third will take about six months:D. Just kidding, the third stage will take about 2 hours of gameplay per match if you play at an average pace and with an internet speed of 33.6 kbps:D.
