Percentage of players getting X Achievement

One of the things I’ve been harking about - and many of you have as well - is new player retention.
While I couldn’t log in, and I was sipping some delicious coffee listening to the amazing Maria Callas, I spotted a little menu that let me look at my “Achievements.”

Note how many seemingly simple ones most people who downloaded the game and played at least once never completed. Looks like an astounding number tinker around with the tutorial phase of the game & ditch it after that.

I wonder how these numbers compare with other games. I know I’ve downloaded a ton of games, poked around a bit, and never came back.
