>You literally had to guess in Pokemon for most of the series.
But it wasn't too difficult to guess what a mon's type was if you understood the common design patterns within Pokemon such as the color scheme and recognize the creatures they're supposed to based on. Mons that look like some aquatic creature and is colored blue are obviously going to be water-types. Grass, bug, dragon, steel, ghost were all obvious just by looking at the design of the mon itself.
