I'm feeling the opposite towards Three Houses. Couldn't really follow what was happening in that trailer, too distracted by how the game still has had no in-depth look at gameplay and it releases next month. I'm guessing it'll get it's own direct in July, but man they're dropping the ball on marketing this game I think.
I feel the opposite, the core of the game is familiar to people largely. Three Houses desperately needed some kind of story driven hype. Prior to this it was mostly just setting.
But if you want gameplay details there's a lot of info out there, actually. I do think a mini direct for it might be in the cards. Also, it is apparently going to be in the Treehouse later.
