I'm sorry, but this would be absolutely great! I loved 'the Awakened and 'Arsene Lupin'. I seriously would love to see an immersive take on the Ripper case just like the previous First Person Sherlock Holme games. I've never experienced something from this perspective either.
So main games of the like are third person, which stirs far from an immersive Detective case.....oh how I miss Tex Murphy.
