Yes but both are made by the same developer. Its more or less the same game with some tweaking and in a different setting. That is why I compared the two.
There's around 4 years difference in age between the two. Skyrim is also a last gen game, if you were playing both at the same time, fallout 4 is likely to feel a lot better and less dated. However personally fallout 4 was not as fun for me as Skyrim or fallout 3/NV. Something just didn't resonate, I completed the main story etc, but I don't think I'll ever return.
Really, I played Skyrim on ps3 and loved it. But didn’t fully complete it. I played fallout 4 to. I think they are diverse in their own right and I am itching to go back and play Skyrim now having just nukaworld to complete.
Couldn't get into this for some reason. Man those giants were annoying. Played Fallout 4 and Skyrim at the same time. Fallout 4 won me over so decided to sell this. Each to their own though. Head added :)
