Twitch was originally launched as a game streaming platform. In their initial days they focused on game streaming including esports tournaments. However, later they started allowing general interest videos just like on Youtube. Nevertheless, Twitch is still the number one video platform for gamers to share different kind of video content, game videos or game streaming. If you enjoy playing games, you can try creating your game videos and share on Twitch. Well, you have to build followers and traffic to attract advertisers and sponsors, and it might take a very long time to do that but if you are passionate about what you are doing, it is doable.
