1) When you highlight one of your settlers, you should be able to see where and if that person has been assigned. (After all, it's not as though you wouldn't be able to just ask that person) This would make population resource management so much easier!
2) While I love the cinematic camera when using VATS, sometimes I wish I could turn it off and simply see all the unfolding action from my own POV - even if it isn't necessarily spectacular. In other words, sometimes I want to feel like I'm in the game world and not in a MOVIE about the game world...
3) I like making my Pip-Boy flashlight white, but I'd like to use colored text for the Pip-Boy monitor. That nit-pick aside, the customization options are already appreciated and go beyond what most game designers have the consideration (and lack of ego) to avail.
And a big THANK YOU to the game designers for not employing that awful raindrops-on-the-monitor gimmick that's so fashionable these days. I'll never understand why designers go through so much trouble to create a believable world for me to immerse myself in, and then ruin the effect my reminding me there's a damn SCREEN separating me from that world. (Witcher 3, I'm looking at you).
Anyway Bethesda, thanks for making a game I honestly can't place second to any other game I've ever played. From my Atari 2600 to Colecovision to Commodore 64 to Amiga to PC to XBox to XBox 360 and now to the PS4... I've never had such a fulfilling gaming experience. Now get busy with Elder Scrolls VI! (And let's go back to Cyrodiil with next-gen graphics!)
