No. I've never bothered to play games like Dead or Alive Extreme Beach Volleyball or something like that.
And looking at the games I recently bought,I find that some of them doesn't even have women at all in them,like Battlefield 3. Of course most have,but no,they are not over-sexualised. (Primal Carnage,Crysis 2,Skyrim) And even if they have a woman or two that are what you would call 'handsome' or 'good looking' like Lara Croft in Tomb Raider,and perhaps suggestive like Citra in Far Cry 3,the fact that these games featured nice looking women wasn't the reason I bought them.
The things that usually make me buy a game is the setting and the gameplay.
Perhaps after these two,graphics also have some importance.
But I don't break it down to individual characters of the game to decide if I'll get a game or not.
