“Big” events are worth it if there is a big enough number of participants, which hasn’t been the case in recent times.
I’d push for minigames. Less work setting them up, break the boredom in freedom-01, some don’t even need the event server to be prepared and constantly checked by the few people who have access to it.
And don’t foget to give incentives. Until last summer, coin prizes made me participate even when I wasn’t really interested. See what you can give players to attract them.
