It's a factor, certainly, but I find the deciding thing is usually the presentation. I need to see 3 things before I'll try a game - Art style, Gameplay example, and a text sample. After that, then I'll take reviews, comments, and rating into account. But I need to know what the gameplay is like, if the writing is readable, and what I can expect from the art style and sex scenes first before I'll play. If all a game is showing me are the sex scenes, then how is the experience going to be any different from going and reading hentai?
