It would make sense that the level of Ian's Wits is important for how successful the book is going to become.Damn that's a rough critique. Maybe Ian's corruption could be cashing in on that sweet sweet merch and franchising when tries to recreate Star Wars instead of Star Trek.
I hope, speculatively, that the success of his novel also takes into account how well the player uses Ian's stats more so than the combination of genres, including charm or even lust if he's willing to essentially sell-out.
