Here are some examples I have found in The Sims Mobile of the game being too greedy. These are my opinions and I'd like to hear what you all think.
Different colors of objects cost more money.
You can receive the same Heirloom multiple times, seems like that could be changed so easily.
The Risky Actions work against you. Your chances of a successful risk action are never as high as they say they are on the meter.
Any deals such as the 'Surprising Choice', will want lots of money from you for very little effect.
The game makes you pay lots of money for things like cupcakes and fashion gems but if traded those for money it would give you little to nothing.
All of these things would be forgiven if the game had more to do in it. Sweet Treats is a fun activity and the prizes are worth it but we need more than click and accomplish micro tasks.
