Depends if you can stand to wait or not. I know I couldn't.
There are very many vocal posters here who ARE waiting for the patch, and consider the game broken without it. However, there is certainly plenty to test out with the game as is. As it is, since the two biggest issues are corruption and the gpt bug, these do not feature much until you start to establish a sizeable empire around the Medieval era and other civs reach governments beyond Despotism, that allow got to become an option. Thus you can certainly safely play the Ancient Era with very little sight of these concerns, and even part of the Medieval Era. Civs like the Inca, Mayans and Sumerians have early UUs, so you could test these out to your heart's content with no effect from the changes to corruption.
I say test it out, but then I am in a minority and rather happy with the game as is. Patches are welcome, but not necessary to get enjoyment out of it, IMO.
