Fallout 4 is still in the "planned to be developed" stage of its life. There's still no announcement regarding the title and if there is any work being done on the game, it's behind closed doors under a strict NDA agreement.
One Youtuber, MrMattyPlays, has published a video that details what fans would like to see in Fallout 4. Some of these suggestions have bigger implications than others, but they're all quite interesting.
Here's a few of them:
- Actual darkness
One fan said that torches never did much in Fallout 3. The player seemed to have a natural aura that illuminated the world around them. It would be nice to see real, suffocating darkness in Fallout 4.
- Larger library of music
Another suggestion from the video is a bigger, more appropriate selection of music. The fan who suggested this cited Mafia 2's soundtrack for both its size and the era of music it draws from.
- Combined speech options
This fan suggestion offers an idea that is quite innovative. Their idea entails multiple stat requirements for different quests inside Fallout 4. For instance, you would need a Speech level of 50 and an Unarmed level of 50 to accomplish a certain task.
