Are you trying to do it cause you already play games 8 hours a day, but want to share that with people and interact with them?
Or do you only play games 1-3 hours a day and are looking for a quick come up?
Basically if you dont play 150-300 hours of games already a month, then streaming will never work out for you. Never seen a successful part time streamer. Ever. Viewers require consistency. If you already cant play 8 hours a day minimum then streaming not gonna get you there.
As far as youtubers/edited videos go. If you only play 1-3 hours a day, this is the more realistic route for you. You better be incredibly entertaining, or incredibly good - or a mix of both. Im talking top 1-3% in the world good. Cause why would anyone watch someone as good - or worse than them unless the person is entertaining? Common sense.
Good luck, but really if you dont have a legit passion for games, your viewers will notice and itll never take off.
