This is only my account and it isn't proof of anything, but I started with 0 marketing experience, knowing 0 people in the medium. I followed Chris Z's advice and I'm nearing 4k wishlists in a few months. Even then most of his advice is the minimum bar you require to get visibility, you still need to make a good game, bad games may get some wishlists, some reviews and some sales but if no one knows about your game then steam isn't going to give you free visibility aside from your launch and then it would get quickly burried because your steam page is shit, your tags are wrong, your capsule looks bad, which means anything you do gets multplied by 0. I'm definitely less clueless from checking his stuff out. Now will I make it? I dunno, but knowing is half the battle.
>has any single person ever followed his advice and had success?
A lot of indies and small studios have been following his advice in the last few years and some have had good sales whether it is because they would have made it anyway or because they apply good marketing I can't say but most (99%) of his advice is free.
