I sometimes participate. I mostly participate for the items as an incentive. I love April Fool?s Day when you can obtain villagers? pictures. I love receiving pictures of my favorite villagers.
I have missed quite a few holidays unintentionally. I too, also get caught up with the actual holidays and miss out the in game fun. I recently bought a second game though and so I'm thinking about TT'ing with it and trying them out. C:
Most of them, except the christmas/toy day stuff. I don't really feel like jotting down a list of everything just for some random items I don't really want and the villagers' dialogues of what they want is really annoying lol.
also I hate pav? with a passion since u get doubles all the time.
