6. Better Hardcore Mode
Hardcore Mode was a good concept in New Vegas but was not implemented correctly. It was very basic, limiting to you drinking water, eating food, having weight for ammo, and sleeping on occasion. These "hardcore" options were the opposite because they were very easily circumvented. For drinking, all you had to do was drink a Sunset Sarsaparilla and you were good to go for about 7 hours in game time. Sleeping was even easier, with just sleeping for 2 hours giving you the strength of a full day's rest. The additions that should come with Fallout 4 should be more severe. In the desert, you need water every couple of hours to survive, which doesn't mean a soda or dirty water, with all the walking you do in the Fallout series. The weight capacity is also another thing they can work on; no human being can carry 10 rifles and a nuclear launcher on their back! They need to increase the weight of these items in hardcore to make it feel like a new challenge.
