That would be nice

As someone who worked in the industry, I can say you often had to FIGHT to get your name in the game credits. And you were lucky if you got a copy of whatever you made, if you did it was months later (likely long after you went and bought a copy because you wanted to play with your friends).

You certainly would not get any free digital content. Maybe a shirt or baseball hat if there were any left over from the launch party (that you weren't invited to because it's only for upper management and investors).
