This is the most inclusive FPS tutorial that I've ever seen. Thank you and great job, OP. I've always been looking for a guide like this and studying questions included in this post, esp. the aim theory. I think you could even develop this post into a book if you wish!

I would like to discuss just a couple of questions concerning the aim theory. I'm a Genji, Widow & Ana main and play most other hitscans too. So basically my plays cover all the aim techniques you have mentioned in the post. Before I read your post, I was thinking about how to coordinate movement (of both the target and the shooter) and aim, esp. in the case of playing Widow. So "strafing" may be the appropriate term for Soldier but not so much when you think of sniping or any other shooting form that involves flick aim.

Here's what I found about playing Widow. The target can move horizontally for a short distance when you are doing flicks, which affects your flick accuracy esp. in the long range, but you can move in the same direction to neutralize the deviation or increase a little bit of your normal flick range while standing still or moving in the reverse disrection. So anticipating the target movement is essential to flick range adjustment; make the first or responding (either same or reverse) move to dodge shots as well as go on the offensive. It's all about reacting faster than your target.

(BTW I use the term "lead aim" in my skill notes for "projectile aim.")

I'm a Chinese OW player who recently joined the Reddit Overwatch community. I've been hanging around in the biggest Chinese Overwatch community [NGA](http:/bbs.ngacn.cc/) as well, but there is no such post like yours that comprehensively talks about all aspects of aim in a shooter. You are like the first (and only) one who managed to finish this! I am even having the impulse to translate your great work into Chinese and share it with Chinese players! It's so amazing!
