I really loved the Jirachi festival from last year. I would like to see things like that, just fun parties and carnivals maybe celebrating certain Pokemon and bringing in elements of Japanese culture, as that is fascinating to me. For wider scale events, I like things that are just a day or two, or three at most, and have opt-outs or other options for participation, like I really appreciate having it as an option that characters can stay their normal age and react to the chaos of the age change event.
