Making women character too sexy is a cheap effect in videogame
Well the issue isn't so much making a female too sexy, we aren't dealing with fashion police in this case.
So much as using a female's sexiness against her or defining her entirely through her sex (unless that is the point of the game, but that is a entirely different entity)... Or focusing on her sexiness to detract from her other qualities.

As for Agarest of War
The Marriage And Sex aspect of the game is to me fine. You HAVE to have sex and if the woman you decide to have sex with doesn't like you... the game treats it sufficiently terribly. As well the game doesn't just have it happen it is a huge part of the games and informs everyone's characters, and every single female character actually goes through significant character development especially if you do go through their relationship.
Mind you that is just the one I saw letsplayed... but suffice it to say...
Dealing with Sex even Rape in a game that handles it pretty directly isn't the problem here. The problem is when games just have it for shock value.
Those skimpy outfits and the things you can make the female characters do though? Ok yeah. The Bath scenes? Yeah...
In fact outside the Bath Scenes, that I never watched... The game does almost nothing to sexualize the female characters outside their clothing... and usually the characters with less clothing have less to show, giving it more of a "I just like less clothes" vibe.
I don't know... I just find less issue with Agarest of War then I do Soul Calibur that made Taki's Panties visible through her pants.
Well at least the one I saw, which was the one with Weiss
