It's more of an Action RPG, like Deus Ex, Dark Messiah of Might and Magic, Dark Souls and so on, are. Ergo, you need to to make sure not only the story and the character development is good, but also the gameplay itself. And to be honest, it's a perfect way to give the player a sense of progressing in the game world and getting better at what he's doing.
Take a guy who really knows his guns, another one for some martial arts/knife/ fighting, some Bear Grylls type of a dude and learn from all of them how a newbie will behave at the start of his adventure and how he should do down the line. For instance, he's having trouble holding the gun right, but later on he figures out some new grips for the gun or he learns them from characters spread throughout the world, stuff that may be useful in CQC battles, other that is useful for medium to long range engagements, etc.
Use pixel perfect, subpixel perfect or whatever you need precision in order to have the armor/clothes/skin/fur covering the body act properly depending on where you shoot or hit your target. Take some clues from ArmA's ballistics, from Sniper Elite's anatomy (which should go in and act accordingly to real life for those hardcoe players), from ArmA's stances, some weapon rest, etc. Take a sneak peak at what Thief did right back in the day, Splinter Cell and other that took the stealth system one step forward, like multiple solutions and non lethal approaches. Look how Dark Messiah combined the environment with the fighting and magic system to give a really good, immersive experience. Basically look around at other games, see what they did good and apply that to yours. And that can be done for Fallout and TES as fell.
Give some love to the AI so that they act like humans will do in certain situations or animals would. Make them smarter, make them in greater number, use AI on the GPU since AMD demo it like 6 or 8 years ago on a HD4850 with thousands of individuals doing their tasks while it also performed real time 3D graphics. Throw some nice physics if you're at it, make it look and feel real!
Yes, it takes time, but Bethesda is no indi developer, they have the resources to pull this off. If you want to do an action RPG then do it properly, if not, stick to clicking on enemies and wait for the statistics to play the part. I for one, would like more control, would like my actions to count, to feel how I'm learning something and how the story develops with my help, because I chose to do that. Time has passed, we have the technology, we only need the will.
