Old Eggplant let out a sigh, not solely because he had seen the game's visuals.
It was the overall atmosphere.
During the "Night of Summoning Spirits," being confined to an enclosed room and considering that Storm Villa was actually more modern in architectural style, Old Eggplant only felt like he had explored an ancient house. After analyzing this feeling, he concluded that people possess the ability to fill in the blanks with their imagination. Often, just a cursory glance was enough for him to flesh out the remaining details in his mind, which made it seem real.
Just like many games, if the background is an urban setting, like racing or war-themed games, the visuals can be incredibly realistic because they have reality as a reference. The top-tier graphics can even achieve a level of deception that confounds the real with the fake.
