So I promised that list and here it is. It's late and it's not as thorough as I'd hoped. I also wish I had images handy to illustrate every point where helpful. So, in no particular order - a subjective set of desired features for Fallout 4:
As you infiltrate a terrorist organization in its American headquarters, you must carefully weigh the consequences of your actions. Kill too many criminals and you'll blow your cover. Hesitate too long and millions will die.
Veteran agent Sam Fisher is back. But he's never faced an enemy like this before. To stop a devastating terrorist attack, he must infiltrate a vicious terrorist group and destroy it from within. For the first time ever, experience the relentless tension and gut-wrenching dilemmas of life as a double agent.
