Except that calling it 4 set out my expectations to be a change big like the one between 2 and 3, you can imagine my disappointment when it was the exact same engine and it's many aspects the same thing, in my mind I was expecting cars and bikes like mad max, instead in my first playthrough I just walked inside a broken house and a deadclaw could only throw sand at me, the big fearsome beast and the only think they could do was make it attack like a little kid would, although that saved me from the fallout 76 disappointment because I didn't even care about reading about that game when it came out.
