Recorded clips or screenshots taken add to the story shared when discussing a game with others. The same is true in real life but people (generally) understand a story told in real life compared to a Video Game. Games can be in any setting, have unique visual styles or mechanics, and generally have more effects, weapons, and moments that aren't/won't be experienced in real life.
Having a way to share your hobby is great and is definitely more accessible now than it was during the Xbox360 days.
Thank you for sharing!
