I have and they build a lot, fast!
In that particular game, they were the point leader and ahead in technology as well. It was 'do or die' time so I invaded their isolated continent. It was a tough fight. After the first or second war, they launched a 'surpise' attack on me in an attempt to recapture their capital. After another couple of wars I had reduced them to a minor power and owned all the wonders they had built. That made me the new point leader but the Celts on another continent had conquered all its rivals and were catching up. I went to war with them to ensure my point lead would hold up for another few years and win the game. I liberated two dead civs and made a puppet out of another city. Probably will have to annex that city and purchase a nuke or two, if I have the gold, to prevent or defeat a counter attack. Thankfully my navy rules the oceans.
On my own continent only one civ was left that was a threat and he was stockpiling the border with troops. I decided a preventive strike was necessary and so yet another war was commenced. Thankfully the terrain was favorable for defense as they swarmed over the border. It took awhile but I finally whittled its invading army down to the point it was asking for peace.

Luckily I haven't yet encountered a completely isolated Egypt, I shudder to think how much Wonders they can build.
