It was made with a modified version of the engine they used in Fallout 3, so it does feel very similar. Of course, the graphics are improved, and so is the combat. The best addition, in my opinion, is the gun mods, which adds to the scavenging aspect by making you collect materials for your mods. There's also the settlement building, but as neat as it could have potentially been, it doesn't make much of an in-game difference.
It does feel a bit like a Fallout 3 DLC, but I don't think that's a bad thing at all. If you liked Fallout 3, I think that 4 is a good investment, but don't expect the wheel to have been re-invented.
