Would you mind hosting more Jump quest events? Also would you try to make different challenging events just like the SMC one?
Name the item/other forms of maple-related trivia. Those are always fun, like the speedtest one or a slightly more organized version of the wheel of mesos event. But definitely NTI sometime.
I might of been the only fan of this, but could you also do a couple of summoning events? I find them to be sooo much fun, and it helps break up the long monotonous grinding. I use to love it when they had summoning events back in the day on Global.
An event I used to run on another server: Depending on the number of interested players split players into teams or leave them separated (around 3-5 teams usually works). Send each team to an unoccupied map (e.g. empty FM rooms). Spawn Giant Snowman (takes 10 damage from every attack)/a mob thereof in each map, ideally with custom HP (they die too fast at default HP). Each player/team competes to see either who can kill their Giant Snowman (or mob of) first or who can defeat the most within a time limit (requires respawning them as they are killed). This does however require that the competing players can whisper the host to say they've finished/are out of Giant Snowmen. (Optional) A small reward could be given to the winning player(s).
