Generally with original games the draw is the premise and the race to get your favorite PB held. Sometimes premades and secrets can be held and used to help write up information [Premade: Lesbian Tennis Star. Secret: I accidentally drowned my sibling when I was six.]
But people tend to look at how well a game is set up, how nice the mod journal looks, etc. Good advertising is key too. If you don't post enough about it, chances are it's not going to go far.
