Good point. I doubt they are using a different ranking system for games above 20 rates.
Afaik, there is only going to be 1 winner right? If so, to be honest, my game is not even close to being good enough to win. So i want to get as much people as possible to play it and get their review so i can do better next time. I feel like our main priority should be to have fun and learn while making our games and playing others.
