Awsome Features In Social Games Today

I have just read an interesting article on listing 6 awsome social features in today's facebook games.

To make a summary, here are what defines a social game:

1. Have your friends in your game world. Having your friends in your farm/cafe/city/hotel is a big fun, and can create a sense of familiarity to you that this game world is really YOUR world. Having some interaction with your friends in your game world is even more interesting.

2. Get your friends' help and helping your friends. One of the most common features in social game that most people like is you can help your friends and get their help in return. This will easily create an invisible linkage between you and your friends, especially for friends that are far away and not meeting often.

3. Team play. This even create a higher sense of linkage. You and your friends forming a team and accomplish tasks together, or going to adventure together. This is the biggest fun that people may not be able to do in the real world day-to-day.

4. Chatting and emoticons. Through chatting and use emoticons to express emotion, you can discuss topics about the games or outside the games.
