I've played this game so many times at this point, and I still read the dialogue no matter what, even though I only do one route over and over again (Katie.)
The story is very dialogue based, the sex/lewd scenes in my opinion are well placed and do well in the places they are placed to push things forward with the story. To me, and I've said it so many times in this thread, that this is the best game on the site and the best VN out there today.
Yes the story revolves around one person (Gloria) and it can get a little tiresome at times because of it, but skipping dialogue is not really something that should be done, unless you know it word for word. I never get tired of running through this game, even though I know what to expect because of how I play.
Some people want words and story, some just want the sex scenes, and others want a good mix of both. But I look at it a different way which I've said in this thread and many others.
Give me a great story, some passionate love scenes (like with Katie in Chapter 6), and some great dialogue, and I'm a happy guy.
