I have a homework assignment about this game. I have to 100% complete the story and then create my own design document about a specific mission that I would want to add to the game at the 50% point. I am asking you guys at what point is the so called "50%" mark of this game. I know it's a sandbox type of game and you get to pick and choose your factions and such, but for the story what is around the 50% mark so that I can know what Icons to use and how my mission should shape up. Thanks for you're time.
