This game is amazing. My favorite game of the year. Simply because of what it makes you feel; True accomplishment. As you grow old, minutes before you die. You desperately try to do what you can to help the lineage succeed.
The tech tree is pretty brutal and very challenging.
I have been surprised at how little griefing is going on.
This game really brings out the best in people.
