Luxuries

Luxuries help draw keep citizens happy and attract them away from other cities, but to a lesser degree than durable goods. As an example of how the satisfaction level of a luxury good works, pretend that you have a city of 80k people with 1 music and 1 rug:

• the rug serves 80k (the whole city) contributing 20% to satisfaction
• the music serves only 40k (half the city) contributing 10% to satisfaction
• the city has a 30% luxury satisfaction rating

People tend to stock up on goods and the satisfaction rating can only change by 5% every year, so the actual luxury satisfaction rating in a city usually won't reflect the luxuries available on the market that year.
