To sum it up I manage to win the water eventually and the guy gives up.
After I watched the rec however, it appeared to me how imoportant water really is.
Especially on this map, and especially between two eggys?
I'm not sure the guy played all that well, and I didn't play perfect either ofcourse. But after losing all that food income he would have to convert his gold to farms while I was on the way of getting my forward camp up, totally halting his production. He decided to resign, and I can't blame him watching his resources at the time.
Exactly how important is water on Medit between two eggy players. Seems like you can end the game right there, perhaps I'm wrong.
