It's not like I necessarily fault SE for it; the team that does the trailer is probably in no way highly involved with the gameplay elements that the game's success is really hinging on. They've got a job to do, too, and I'm sure in their mind, they can't sit around waiting for validation from the playerbase that the rest of the game looks good. But it feels like bad timing. People are still very skeptical about the game; they want to see substance. Flash like this is great for increasing existing hype... it's like a multiplier bonus. You don't play it until you've nearly maxed out the base stat.
Ok, now we're going to get slash fiction of Wint x Kachi somehere... rule 34 and all...
Never confuse your inference as the listener for an implication of the speaker.
Good games are subjective like good food is subjective. You're not going to seriously tell me that there's not a psychological basis for why pizza is great and lutefisk is revolting. The thing about subjectivity is that, as subjects go, humans actually have a great deal in common.
