Sure it does, and there's nothing wrong with that. There's nothing wrong with throwing in exceptionally attractive men or women with appealing physical features to augment interest in one's video game. I think MGS3 did this very well. MGS3 was an amazing game with fantastic gameplay and an incredibly captivating and emotional story.... oh, and Eva was FUCKING HOT (yeah I said it, what, SHE WAS!); did that cheapen the game in anyway whatsoever? Fuck no. For me, it made it more enjoyable. I was still very immersed in the game's fantastic storytelling, but at the same time, whenever Eva came on screen, it made me just THAT much happier!
What I'm saying is the use of eye candy in a video game can add to the experience itself - i'm not saying replace quality storytelling and gameplay with it, all i'm saying is the use of these visual tools can ENRICH the game without abandoning the quality of the game itself.
