I think this Halloween, we should still have trick or treating and hunting ghosts for Candy, just like a traditional Graalloween. Instead of a witch flying around, maybe a headless horseman?
Definitely open Club Crypt and definitely open Onnet like previous years, also, maybe put some costumes in Taylor Richards?
With the Headless Horseman idea, I think it is time for a comeback in randomly spawning NPC's. It could possibly give you riddles to solve or even a quiz? The Headless Horseman could just give you a cool hat, morph or mount if you guess all correctly.
Maybe certain baddies could drop pumpkin tokens, so when Club Cyrpt, or any other shop opens, some items could be bought with gralats and some with the tokens? I also hope the Halloween tile set is here this year!
Just blurting out ideas here, sorry if I confused you all.
