Some of my friends are independent game devs. They are good, very good, but many complain about a recurring problem : "How to promote my game???".
… And the most annoying part is that if they don't promote their games, it won't work. To highlight the problem more clearly: Working weeks may be wiped out due to lack of promotion
Just consult Quora to realize that this problem affects all indie game developers
I'm not telling you that my solution will revolutionize lives, but it's a good start. I created a simple listing of the biggest blogs, magazines, facebook groups, reddit channels, video channels (Youtube, Twitch) & marketplaces to help them to promote their projects.
