There's no one else who makes anything like Bethesda does. It's not going to be cutting edge technically. It can't be when you work on the same game with that much content for that long. But it's huge, you won't see it all in a playthrough, and you can play the same game a completely different way every time.
There are common elements, but compare it to other big 3D open world games. Far Cry and Assassin's creed ship the same game every year with small tweaks. There are smaller budget ones by smaller studios, but they're a lot less polished mechanically than Bethesda and don't have anywhere near the scale. Bethesda is reusing something like gun mods or base building, but with completely different themes and adapted to completely different gameplay. They're not cloning. They're iterating.
