I strongly dislike that this event requires people to adjust their lives to the game. It's highly disrespectful of people, it's stressful and unhealthy.
I already find the playground games to be highly unrewarding in regards to gain vs time spent playing the games.

There's a difference between trying to make items "exclusive" and making a game satisfying to play. This isn't rewarding at all, and as pointed by others, it's stressful to try and figure out if the game is worth the time required to play it without knowing what the mechanics are/are going to be.

Evolutive mechanisms should be funny but this is mostly frustrating. Please, at least remove the timers for the daily quest errands.
