The problem isn't the game engine (which, by the way the thing you think you're complaining about is actually a good thing as it shows that robust change to the game engine market has made them offer feature/quality parity, and I think there's actually more game engines now than in the past; IDtech and then Unreal dominated, but now we've got Unreal, Unity, CryEngine, and I think a few others, and then of course some companies do their own like Dice/Frostbite, Valve/Source, etc; and game engines are now more versatile so they get used on more variety of games), its the game/art/visual design. Larger game development has become more conservative, which has lead to rampant problems (looks, design, story, characters, etc). Companies aren't willing to gamble on tens of millions in development cost on doing something really unique and interesting.
I would think that, but then something like DOOM comes along and the engine seems incredibly robust and scales nicely over a wide range of hardware.
It will be very interesting to see if Doom will have a profound industry wide impact, or if it ends up just being a standout that ultimately doesn't alter things. I don't see it having the impact the original can (which granted few games feasibly could), and in many ways, the reason it is so good is because its a shining example of the old way of doing things, and so I wonder if it might be a last hurrah before we see a truly transformative change. But, there's a lot of things about it that seem very forward thinking. Excellent game engine and game design, that I think will actually fit in excellently with say VR (where the visceral nature of the game will get further enhanced, and the physical toll will play right in with the gameplay in that it is about fighting off an overwhelming horde of demons).
Ultimately I think it will be in between, but also the most optimistic. Simply put, there is place in gaming for the old and new, at the same time, and that many of the old ways were fun not because that's all we had, but because there are basic elements that make them fun.
