Game as a service

So i read a presentation of Scott Brodie about "Designing game at the service of humankind". There are a lot of great idea to provide long lasting game. On my opinion, game is a service for people is enough.
What characters of service that we can apply to game?
1. Listen to your customers
Everyone wants to be listened, especially when they use a service. I saw a women who come to a salon to watch her hair, after finished, she feel happy a lot and share the feeling with service staff. We should support that function in our game. The more user feel being listen the more sympathy they are. Just an email to support team but mean a lot.

2.Greeting customers when they comeback to your game
Greeting make the customer feel the respect. In KFC stores, there's an employee who just stand to greet new customers come to their store. Just a simple sentences, "well comeback" a lot of difference it make.

3. Remember each user
It's like data mining. Remember your customer habit to suggest them what they always want. Favorite list and recently list is good example. Think about your individual customer 's need. The more your remember about your customer, the more they think you understand you.
