These other platforms you mention don't really want to see self-promotion, often times it is regarded as spam. All of them are also working very hard to make it so that you have to pay them to have any visibility at all.
This platform can be seen more as hosting and selling. It makes available some measures of promotion, like dev logs, but these are not very effective to that end. A lot of good games get lost in the traffic here.
If I do the exact same thing as these other sites, then yes. I was simply trying to get a feel for what is needed by developers in the industry. Marketing was just one of the many options I listed there. But there are many big name marketing platforms as well. I appreciate your opinion that marketing is a challenge as an indie dev and as one myself I agree. I was just stating how there are several big name, established sites that help promote/market your game already. But no matter how good the platform is, if you don't have a game that people want to play, it won't become successful.
If a platform could magically make anybody's game a hit, then anybody and everybody would be millionaires from making games.
And to follow up, I'm not saying that it can't be done. I 100% agree with you that marketing an indie game is frustrating. There are definitely some great games that go unnoticed. I was just saying there are only so many tools a platform can give you to become noticed and existing platforms provide most of these tools. The rest is on you to stand out.
