I'm reminded once again of that episode of The Simpsons where Marge gets Itchy and Scratchy off the air by making it kinder and gentler, but when the decency groups wanted her on board to prevent Michaelangelo's David from making a tour stop in Springfield, she declined, saying "everyone should see it." Then there was the whole "you accept David, indecencies and all, yet not Itchy and Scratchy, indecencies and all?"
I'm cool with fanservice. It's a good gimmick, especially since it provides a lightning rod for discussions like these every time. Conception II is certainly not hurting from this publicity. My only issue is if you were to hypothetically strip away the gimmick, is the core game any good? It's like, when KISS washed off the makeup in the 80s and just played as themselves, they sucked. They were just like any other cookie-cutter band. Think about it. KISS is really a mediocre band in terms of musicianship or even songwriting. But put the makeup, the costumes, the pyrotechnics, etc. back on, and they were cool again.
On the other hand, if you were to take away all the funky stage props that Red Hot Chili Peppers use (e.g. lightbulb hats, Flea buck naked, colorful costumes, etc) and just have them perform in street clothes, they'd still be fantastic because, at their core, they are an excellent band with skillful musicianship and songwriting.
EDIT: And, yes, while there are plenty of eroge that are nauseatingly degenerate, just plain stupid, or both, there are some that are excellent. Crescendo still remains one of my favorite VNs.
