What are my fellow Civ players opinions on city ruins? I normally leave them in my cities BFC hoping to get the research event from it. But in my latest game I burnt down 5 of them and left all of them. Some of them were in prime grassland riverside spots robbing me of a nice fully cottaged tile by end game. I've only managed to get the research event once this game even with all those ruins so I'm re-evaluating my stance on them especially when they are located riverside.
