"Let's Play" is a term used on video sharing sites (such as youtube.com) by 'Let's Players,' they are people who record themselves playing through video games. Generally from the very begining of the video game's story to the end of the game's story. Yes, this does sound just like a regular "play through" or a video guide of how to beat a game, but what makes Let's Plays different from regular play throughs or gaming guides is that these videos have commitary (usually live, meaning that the commitary is recorded at the same time that the game play is being recorded). The commitary in Let's Plays are often humorous and entertaining. They also might often entertain and thrill you so much that you might even want to buy the game that the LPer is playing yourself. If the LPer is doing everything correctly, watching the Lps should be as natural as having a good time with friends or maybe it will be even more natural than that. If the LPer is dedicated to what they do, they will generally stick to a daily/ bidaily uploading schedual. Sometimes even a weekly one. If the LPer is popular or has been LPing long enough where they know what they are doing, sometimes they will do 2, 3, or even four different game LPs at the same time!
