Well, I'm currently not interesting in making events. But as being Game Saga in other games, I've created many events. Here is 1 that aeria team might publish.
"Champion of the week"
This event will require GM to select 8 teams each week and there must be 4 members per team; having 2 alternative backup will be fine. In this tournment, 8 teams must battle each other, winner will advance and loser will disqualified. The team that win and reached to the top of the tournment tree will have to battle their own team members. The member who beat their team will be rewarded some rewards and the title "Champion of the week". They are not able to join the tournment again for 1 week after the winning week.
