A "Let's Play", also known as LP for short, is simply someone playing a video game while providing commentary. This commentary can be about the game, or it can be vlogging, or even venting.
There are many LPers on YouTube, some with a few thousand subscribers, or even tens of thousands.
Some well-known LPers are NintendoCapriSun, 900RedYoshi, Chuggaaconroy, NateNaterson, and ProtonJonSA.
[Please note before visiting their channels that most, if not all, use strong language in their videos.]
This brings me to Retsupuraes. "What's a retsupurae?" you may ask. Well, a retsupurae is like an LP, except instead of playing video games and providing commentary, they take "bad" LPs and mock them.
The most well-known retsupurae-er is simply known as retsupurae.
Any LPer who has been retsupurae'd has lost all respect, but some still remain a large member of the LPing community.
I hope you enjoyed my short-ish intro to LPing, and if you want, you can check out my LPs at wiigcnds.
Another good LPer (technically pair of LPers) is WiiRikeToPray. Also, I've never heard of "Let's Quickly Play" or anything along those lines before. :o
