The bitcointalk Gambling (e.g.) "ANN Thread" forum is a mandatory place where your project must be presented, at some point or phase of the project. That is an "Unwritten Rule" of any trusted project.
But best of all, is that some projects that do not go through here when they should, end up exposed by third parties, for false or good reasons, criticize them in such a way that they take away an important traffic of players, if not the most important that can exist for any project that exists related to the blockchain.
Really something as simple as making a thread of your project in the forum, "must" have an important consideration, as I already said in any phase of the launch, and if possible add financing for advertising, signature campaign, social media campaign , etc, any project must take marketing seriously, like the project itself, and that serious marketing must include the bitcointalk forum.
