I played in a FFG Star Wars group for a few months and it really was so freaking unintuitive the symbols and colors that they used. It felt like they wanted to simplify things but instead you had to keep track of green, yellow, purple, red, black, blue dice and like 5 or 6 different possible roll outcomes, you have to remember which symbol cancels which and also keep track of which skills are adding or subtracting dice…it really made me miss the simplicity of a D20.
