Yes, video games have ceased to be a mere hobby to become an effective medium, not only for developers but also for players. Most likely, the idea sounds silly and, frequently, it seems so, most people do not know about this possibility, and some of them react in a mockery or adverse way since for them video games are nothing more than that, a game.
There are basically two ways to work as a player: the first is, through the “lets-play”, which consists of getting people who like to watch you play X video game, this can be done through YouTube and Twitch, whose main difference is that YouTube is an excellent video library, while Twitch is a massive catalog of people doing live things.
The second form is like pro-gamer, which is almost equivalent to being a professional football player, basketball, tennis, etc. requires discipline, a lot of dedicated time and many other factors, because as in traditional sports, not always having passion and dedication is a guarantee of becoming professional.
Are e-sports based on pro-gamers? The professional field of video games has grown enormously in recent years, due to an exclusive synergy of video games. Let’s take football as an example, to play a match similar to the professional one requires 22 players three umpires and a ball (leaving aside alternates and uniform) until those requirements are met will not be a game on equal terms to the professional, maintaining proportions of skill and professionalism. In contrast, there are video games that anyone with the right console can play and each copy has the same characters, scenarios, and statistics. In this second case, the only difference is the player’s ability. And that’s why e-sports have grown so much; because their pre-entry requirements are super simple, which everyone can get in, but getting to the top is more laborious, like any sport. This also influences lets-play, as they are often taken into account due to two primary reasons.; for entertainment or to study. The first is the one that is played for entertainment and fun, focuses on the experience and exploration of the game, rather than on teaching how to carry out specific mechanics or techniques. It focuses on games that have greater flexibility when dealing with them as Sandbox (which are open-world video games, where the player has freedom of how and when to deal with the elements of history while exploring the world), thus allowing even the same game to differ between lets-players and the viewer when playing the same title.
The second is the one who does “tutorials,” which focuses on explaining the aspects of the game mechanically (i.e., the specific distances and values of abilities of the characters within a game, the length of a jump, the force of a blow, the frames of action, etc.) These are used when you want to learn about a given game/character; they are inherent to competitive games. I will take as an example league of legends, where there are about 139 champions, each with four special skills and a default attack. Also, there are approximately 247 objects, of which you can only buy 6 per game and not all serve all the characters. You get the idea of how complicated it gets for one person to try to learn all that, don’t you? That is why there is this second branch of lets-play, so you can learn what interests you about the character without having to search in forums full of repeated and unexplained information. Instead, you will see a series of videos that show the action of what you want to learn and will help you to replicate and internalize that knowledge more efficiently.
