A lot of things could be called vulgar, or pandering to your audience cause you know they will like it. There is nothing wrong with that at all.
For instance do Mithra need to be in skin colored underwear when they have no gear equipped? do Galka need to be practically naked? they did it cause it's fan service, there was no reason for it other than that. you could say it is vulgar and pandering to perverts, or is it just accepting reality of what people want?
What about ff14, is anyone gonna say that game isn't hardcore wall to wall fan service? and that being so, played a large part in why so many people like the game today.
People like it, it's good to give your customers what they like and there is nothing wrong with people liking it, cause we are wired to like it. Also it's a very easy way to get lots of attention, it does not matter how good your game is if nobody knows it exists and guys (who are the massive majority of video game buyers) like t&a.
As much as I and most people may like fan service in games though, it's not going to sell a bad game. For Nier Automata (you can literally blow her skirt off) the demo showed how amazing the gameplay was, Stellar Blade demo looks great, First Descendant looks like a great warframe clone and new Vindictus combat is amazing.
The booba is the hook, and the gameplay is the reel in.
This is the video that got me to pre-order Steallar Blade:

I played new Vindictus defying fate and it's 50% titties and 50% dark souls combat, also great fun game.
