You’re sitting down to play your favorite game, you pop open the box, and you start pulling out the pieces. It’s then that the pre-game activities begin, starting right off with the squabble for who gets which components.
Because game pieces innately come in colors.
We’ve been trained through years of playing that color is how we recognize which pieces belong to whom. When a game like Tigris & Euphrates comes along, which marks player pieces with symbols instead of colors, it’s a problem. I don’t know how many players I’ve seen who didn’t understand that they couldn’t be blue, red, black, or green in T&E. Personally, I found that I had to make my brain leap through strange hoops the first time I played that much esteemed game because symbols didn’t make sense, and colors do.
