You do realize such a TV ad reaches a far bigger audience than all those game trailers combined?
And what trailers are you even talking about?
Of course it does, but what company like Nintendo actually tries to reach a general audience by showing fanservice on TV?
The argument from people has rarely ever been that sexualizing characters is meant to advertise the games on TV, the argument has almost always been for nearly every game that sexualizing characters is a subtle marketing tactic to broaden the games appeal or get people to buy the game. For people who believe this, it's a subtle marketing tactic mostly targeted as a gaming audience. Not the kind of thing you'd just show on TV.
I seem to remember pretty clearly that one of the first trialers for the game had a part that subtly emphasized Pyra in a perverted way, but honestly like I said, I'm not for the argument that Monolith or Nintendo are sexualizing characters to advertise the game. I don't care if they are, I've never cared, and it's arguable that they aren't. I'm just pointing out that, if someone who held the opposite view as you wanted to argue that they were, your original comment would in no way contradict their statement.
