I don't know... Maybe 10% a day is a bit harsh.
And what if you can't satisfy the request, say for your example, you don't have any job center or worker to load?
I agree that non players should be penalised. But there is already something for that no? Isn't it the purpose of the Luxury tax? If you let your city alone too long, you'll get more and more new citizen thanks to the popularity. Then, you'll get the social service price going up and when you get to 0 SIM, you pay the Luxury tax ?
I agree that it should be a bit more drastic. You can let your city alone for quite a while if you planned a bit.
And there should be a grace period. Sometimes, you don't connect on a weekend because you were at your family house, or on vacations... Or you had a hard working day and don't want to be on your computer anymore. Even the mayor has weekends ;).
Overall I like the idea, but something in between would be great.
I agree, maybe something softcwould be better. Anyway, social services price is too slow to reduce income of ruch players not playing for months: they could buy many Social aid office and stop playing, then waiting some months, taking the income and playing one day only. DCity needs a mechanism to be a real play to earn or taxes and token value will always remain static.
