Playthrough 

A video with a more relaxed and casual focus on the game that is being played.
A playthrough is often a video with live commentary on and is the most popular form for YouTube gaming videos.

A playthrough is not to be confused with a walkthrough as a walkthrough is a strategy guide and a playthrough is not.

Playthrough is considered the same as a "Let's play" and is also spelled "play through" or "play-through"

Guy 1: Did you see that guy's Metro: Last light walkthrough?
Guy 2: Would hardly call it a walkthrough, he was just messing around and it was obvious that he hadn't played the game beforehand, i would call it a "Let's play" or "Playthrough" if anything.

Play through 

A phrase borrowed from the golf course. This gives permission to an individual or group to discontinue listening to your boring discourse about yourself.

Will: ...and I won "Best Lawyer" award again, and I have 704 friends on Facebook, and I've never suffered, and once at the Eiffel Tower..... (then notices the attention of listener is wandering) ...oh, that's OK....you just go ahead and play through....and I took her picture at the catacombs...and I'm handsome...

play through 

When a male is having sex with a female and his buddy comes along. The male in mid coitus will stop before he is done and let his buddy have sex with the female. After his buddy is done the original male will continue. Usually happens in a train.

I was late for the train on your mom but Derwin let me play through
