Increase your Fame level 100 times across all your zoos.
This achievement requires that you earn a cumulative total of 100 Fame Rating increases across all of your zoos in Campaign and Challenge modes. Fame increases in your zoo by doing just about anything that involves expansion, happy animals, or upgrades. This will unlock naturally when finishing Challenge and Campaign modes, but if you want to unnecessarily grind this, it is easiest just to keep starting zoos and advancing to level 10 or so by constructing buildings, as initially Fame level increases are quick, but slow as you expand your zoo towards the zoo limit.
