When video game designers are trying to sell more copies or appeal to that prime target young males between the ages of 18-34 audience they include fan service elements in their game, which are often taken way too far.
Want to know what taking fan service too far looks like?
It pretty much looks like the entire Dead Or Alive series, but especially that cheeky DOA Xtreme Beach Volleyball game released by Koei Tecmo- which was basically all about boobs.
In fact, when it comes to fan service most game designers go straight for boobs in skimpy bikinis, which is not only a cheap way to lure in teen boys with raging hormones- it's a good way to make your game fail among serious gamers.
There are exceptions to the rules like Metal Gear Solid V, which is still seen as one of the best games in the franchise despite the fact that Quiet the mute sniper wears a bikini to battle.
They could at least try to make the sexiness work in the storyline like they do in The Witcher games, but maybe Quiet is so quiet because she's almost naked?
