I really think you can build off of this so much more than just spawn and kits, what if we had seasonal crates and seasonal spawners, like the seasonal crates can have Halloween 2020 tags or tags like Spooky that can’t be bought in the shop but only if received from the crate, which could make them worth somethin. For seasonal spawners what if we had like during Christmas snowman spawners, Halloween bat spawners, thanksgiving villager spawners and more. You could also do seasonal maps like say the whole month of October is the Halloween map, November thanksgiving map, December the christmas map, January new years, February valentines, march st patricks, April and may spring map (1 long map), July Independence map, or July and august as one long map called the summer map, and september the back to school map. There is clearly a lot that can be done off of this.
