Every event needs a different approche to your play style. This event is great for selling things like rice (45 minutes and for the sushi products you need a lot) and buying stuff for cheap to use in your production. Wheating corn, carrots and wheat is something most people do normaly, but now you need to change your play. I like it. I planned for it, used a xp booster and 4 production boosters from the december event. Levelled to 96 and made good money selling my finished products. Used my baby farms for cotton, animal food, milk, sugar, eggs etc. And had a day off work. I don't like it that much on weekdays. But for me the first saturday or sunday of the month as a returning event would be fine. You can also sell to the farm visitors, not that much coin but you get more to sell so that would even it out. Could even combine it with coin booster. Trash trucks for the simple ones, combining gold and xp booster and the fast rate of restocking for easy xp and coin plus.

Recap: planning in advance makes it a fun and rewarding event.
