Here's Seamang64 playing Civ 6 on his laptop, able to claim that he "built Oxford University in Oxford in Oxford University in Oxford".
It's not the first time this has been done -- remember the guy who built Petra at Petra? -- but this one sounds a lot cooler when you say it out loud like that.
I think the only way a line like that can get any cooler is if any German readers want to take a swing at building the Ruhr Valley in the appropriate spot.
He took the pics inside the building the centrepiece of Civ VI's Oxford model is based on: the Radcliffe Camera, a library that dates back to 1748.
