Potential challenges include ensuring that the simony and diamond themes are well integrated and not clichéd. Also, balancing the intensity ("hardcore") with accessibility for casual players. The game might offer multiple difficulty levels for investigation tasks.

Possible gameplay features could include investigative tasks like forensic analysis, following leads in luxurious venues (art galleries, private sales), uncovering secrets of the elite. The "handomecore" aspect might influence the game's aesthetics—high fashion, sleek visuals, maybe a noir or cyberpunk vibe depending on interpretation.

The title "Do New" might imply a reimagined version of an existing property or a brand new story. If it's a reimagined game, perhaps a sequel or a new take on the Simony Diamond character.

I should also consider what makes this game stand out. Combining the luxurious and corrupt elements with a modern or classic detective approach. Maybe a unique art style that merges "handome"—attractive and robust—design. The game could have a strong focus on fashion and gadgets, with the detective using high-tech tools in a stylish way.

For the plot, maybe the player is a detective investigating a diamond heist or illegal trade that's linked to simony—perhaps corrupt religious figures trading sacred relics for diamonds or money. The detective, "Simony Diamond," could be a character with a personal stake, like a history with the diamond trade or a family connection.
