The long-running indie series Adventures of Sherlock Holmes has been scratching that open-world detective video game itch for over a decade, long before L.A. Noire. In this series, Sherlock Holmes solve a variety of cases, many of which pitted him against other famous characters, like Arsene Lupin, Jack the Ripper and the Cult of Cthulhu. Besides giving the players the chance to solve mysterious crimes, many of the games in this series also offer the chance to roam around places in Victorian England.
Frogwares has done well in meticulously researching the history of 19th century London. But when the sixth installment, The Testament of Sherlock Holmes came out, more effort and attention to detail was given to really create that authentic look for the HD generation.
While not entirely an open world game, players are still free to roam around the downtrodden Whitechapel District itself to see the dark Gothic buildings and the dreary economic state of much of the city. This great attention to detail turned this indie title into one of the best detective games of all time.
