Solution

The first step is to identify that each character shown in the task is featured in a specific video game. For instance, Silent Hill 4, Persona 5, Team Fortress 2 etc. The next step is to replace the characters with the number from each game title and solve the resulting sudoku grid. The last step is to, for each video game, trace from the first roman numeral consecutively to the next for each sudoku number. This gives you the letters mouldings which is also the answer.
