I was mostly in charge of defining the visual style of the game. My responsibilities included, character design, character building and texturing, level concept art, level textures and lighting, prop design, building and texturing, and scheduling and art team management and instruction.
Lets begin from a pure art related question.
Lately I become more and more interested in texture creation. In the game one may find fully drawn textures and the ones made from photos. In the case of our game we wanted to create the most believable environments in context to 1930's Ireland. We did extensive research on Manor Houses and Irish architecture and landscape. We decided it would be best to scan and manipulate our textures rather that hand paint them for realism.
