In lawsuits if they can't keep that promise? Several thousand, several refunds.
I'm digging people thinking that editing a trailer or even a letsplay, or a gameplay trailer showcasing new features is 2 hours of work. Lol. They have to play the game, capture the footage, run through it, log it. Have a team look through it, pick best segments, do a paper edit, write dialogue for the trailer, record it. Then edit, then export, it's rough, preview, make adjustments, make it tighter, export, preview, have your graphics team do titles, lower third in style of the game, pop ups showcasing the changes, sync them to the voice over, export, final preview, final notes, final edit, final export, upload. You're looking at least a week.
Or hire one of the YouTube kids who do those amazing kills in the game, on consoles, gift them the game, have them record a thing or two, upload. You're looking at 2 weeks then. Getting comfortable with the controls, practicing the kills, uploading the footage, make sure everyone is happy, and promote.
Fact is that it's a hell of a good game that was a major surprise with many, and a lot of people will double dip mainly because of that.
Press release is also a lot of work.
