My thing is, I do not see someone who is so plugged into gaming that they will watch the TGAs see one trailer out of the dozens, get hype and proselytize it for a month nonstop...YET at the same time pays so little attention to gaming that the miss literally every outlet on the planet going nuts about how terrific HI Fi Rush is. I can see the opposite of dozens of "who asked for THIS?" videos and click bait.
A trailer a month earlier wouldn't reach some unwashed masses who would never hear of the game otherwise, because if you're watching the TGAs, youre already plugged in. Even if you missed the Xbox showcase, you weren't going to miss the tidal wave of 9/10 reviews. To reach the folks who would miss that hype they'd need a BIG marketing push. Like... for months, about the only point of discussion in the Xbox sphere was HFR. If you missed the hype, a TGA trailer wouldn't reach you. Getting that going a month earlier wouldn't suddenly make it break into the mainstream, unless you did a media blitz of the kind Microsoft barely does for its bigger titles.
That's my thing, to actually make Hi-Fi big, they'd either need to invest in a marketing campaign for an AAA production, or release it of PS5 and hope the hype drove engagement there.
Both of these seem like the obvious better course in hindsight, obviously. But just announcing the game wouldnt.
Tango can't. It's dead. Johannes and other team members can and should.
