Recycled is better than nothing because gems.
The short times, combined with high prices...it's like it is designed to make people quit playing the game. Throw in side goals and ugh! Goals are more chore, less fun.
50,000 for one appliance?! Newbies can't swing that, even if they had enough good neighbors sending them parts (which they don't.)
Move those side goals to a different week.
Drop the cost of appliances.
Lengthen the goal time.
