The system was undesirable by a lot of players (I think) because of how difficult it was to collect the candy.

Last year's system worked (in a sense) as they were trying something new. But I agree with the people who say it was repetitive and got tedious quickly. Maybe use the same system but differently?

Something that could be cool (but may not be able to be done since Halloween is right around the corner) would be if the NPCs would give you tasks in order to receive candy. Not really sure how this would work, though. Maybe something like "Bring me 'X' loot item" or "Bring me 'X' bug" or "Bring me 'X' food item" could work, but then again there is only so much you can do with this.

It also seems like the NPCs are decorating for Halloween. Maybe one of the tasks could be helping them decorate their homes. But again, this would probably take time to design and script, and I'm not sure if there would be enough time for this.

Something that could be cool is a "Haunted House" competition, where players decorate their houses and try to make it as spooky as possible and submit their decors for a contest. Whomever has the spookiest house could win a prize of some kind. I don't know how this would be organized, though, but it would be pretty fun.
