Any games that require teamwork actually can provide such learning points of how we can work together in real world context as well as other life skills. Games like world warcraft or even Lord of Rings can just provide these opportunities. There are many more. As a current school teacher with many difficult students, I saw how my students were used to fight physically, they started to learn how to work together as a team after allowing them some free time for multiplayer games. A good game leader can also spot opportunities and lead his players together. Just my humble thoughts. Everyone can have their own opinion. Online games can be a tool but it is definitely not the only way.
