Yes, streamers do play a huge role in what players choose. It has become a real trend, and now streamers can greatly influence game sales. People often buy games because they see how cool they are played on streams. This works not only for big games, but also for indie games that might have gone unnoticed without streamers. I read an interesting article that talks about how streamers are changing consumer behavior and gaming trends. You can read about it here https://www.gamespace.com/all-articles/news/how-american-streamers-changing-consumer-behavior-and-gaming-trends/ . This has become a real marketing tool in recent years.
I've noticed that streamers are increasingly influencing people's game choices. When a famous streamer starts playing a game, everyone immediately starts watching and buying it. This applies not only to popular projects, but also to small indie games. Why is this happening? Why do people become interested in a game just because a popular person is streaming it?
