Marketing is important. But marketing should be done by marketeers. Not by devs, who have their own job to do. And not by HR checkbox hire rejects, either.

Get a marketeer to look over stuff already made, photoshop some stills and gussy it up, hire some booth babes and dress them in (in)appropriate cosplay of your lead mascots and characters, show off some concept art or storyboards, and have that marketeer gush about how awesome the game is going to be because the concept, the story, and the gameplay.

I'll take my $50,000 consulting check, thanks. I just told every dev what they should be doing to have a successful display. AAA dev with money to throw around? Don't hire random tokens, instead, MAKE random tokens: Statues of cool stuff in the game, figures, keychains, plushies. For the cost of one Woke Consultant for a single year, you can make approximately 10,000 plushies.

So, marketeers, riddle me this: What would get more sales: A woke consultant who does an HR struggle session meeting on the E3 stage, or the accountant on a quiet day standing around in nerd-infested areas with a crate full of 10,000 plushies of the cutest mob in your game handing them out saying "buy Fallfort Of Duty 7.3! Free plushies! His name is Janto and he's adorable!" then posting that video on youtube?
