Just because you can build something doesn't mean you should. If possible, just reload one of those games, don't build Louvre, and see what happens. Its not worth that hammers just for artifact slots.
Those Wonders all do dramatically less than other earlier, cheaper wonders. Being easier to beat the AI too doesn't make them a good choice, if they are weaker than balanced wonders they are too weak.
Lets start with the Louvre. Just build Uffizi instead and get basically the same wonder for fewer hammers. (I really think Louvre should give a free museum, since it is you know......a museum)
Now lets look at Uffizi. I'm going to asset that the golden age is usually going to be the better use of the wonder. Notre Dame costs less, gives you a cathedral, and starts a longer golden age. Either Notre Dame is way OP or Uffizi is bad.
Now looks at globe theatre. Some people might prefer a writer to an artist, and its cheaper than the other two, right? I would say Globe Theatre is at best just okay. Its really not great if you make a great work. There is a decent argument for the cultural boost, being like 5 turns ahead in social policies can make a difference, but its still really weak in my opinion. In an era of amazing wonders (Leaning Tower, Chichen Itza, Porcelain Tower, Sistene Chapel) you just have better things to be doing with hammers.
