You can speak for yourself.
I don't get bored of IanxLena because of the
writing. The writing can make the scene super hot even when you're just looking at a static 2D image, which is actually just a traced screenshot with some coloring.
There are plenty of games of much better sexier graphics but people keep coming back to this game for the writing, drama, and engaging characters.
I agree that
recycled scenes will quickly become
boring, but I don't see anything wrong with
reusing assets when the
writing can change the context of the scene.
