a WoW like Darkmoon Faire every weekend with minigames like the ones you suggested including daily quests, reputation, tokens and buy fun reward.
The Winter and Summer events are really good and a great grind / time sink but it is temporary, we need features like this in the game permanently.
The game it’s sandbox is quite good for a Darkmoon Faire talk to npc spawn in the whack a mole arena auto equipped a themed 2H Warhammer. Archery or Firing range same design method talk to npc auto equip and shoot the targets.
I agree that this type of recurring event is very exciting and always participated in. I think it would be a good addition to have something like this.
