They usually focus on only a single game. Another type of professional gamer is a streamer. A streamer makes money by posting video of them playing games. These videos are often done live and put on Twitch or YouTube. They make money from viewer donations, sponsorships and ad revenue. Video games can be played alone or with others. With the internet now widely available, playing games with other people is now extremely popular. Single-player games are games that are played alone. These types of games traditionally tell a narrative and take the player on an adventure or through a story. They often present a series of challenges that get progressively harder.
These are self-contained experiences and are paid for upfront at purchase. Most games have a single-player campaign but may also include a multiplayer component. Multiplayer games are games that are played with a small group. Typically, they have between two and 100 players at a time. They usually take the form of one person or team against the other in matches. They are designed to be played competitively, and there is no story between the matches. Multiplayer games can be played locally with people in the same room or over the internet. Multiplayer games may be paid for at once in a purchase or be free to play (F2P) and have microtransactions to buy small items to fund the game.
