France and Egypt are definitely the worst civs in the game without a doubt.
Egypt is the stupidest civ I've seen in my life, get a bad wonder and you're pretty much screwed and lost the game before its begun.
Get no desert and you've lost your other civ bonus.
On the other hand get a good wonder (like colosus) and you've just got a free ticket to a win.
Then there is france, which is just flat out bad... take england, remove the 50% more powerful archer, and free use of dye resource right off the bat... remove the free double naval support and free +1 hill bonus --> voila you have france!
