"In your game world there will be purple ambient orbs that float around the game world. These orbs represent people on your friends list and it shows where they are in their world as they're playing it. To invite them into your game you can just go up to them, invite them, and in just a matter of seconds they've entered your game world"
This blew my mind. Most games I play the disconnect between two players playing seperate games is so great that even if there is the option of co-op the hassel of leaving my game to enter theirs, or vica versa, is so great that we end up just sticking to our own seperate games, unless we schedual it otherwise.
With this, that barrier has been broken and the full potential of co-operative play is fully actualized. Its just brilliant.
Who I am and what I do is not as important as what I am and why I exist.
