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.
