I have been playing the game for many years now, and am still enjoying it very much.
I have a suggestion: in the Marleybone Big Ben, one has the optional possibility to "spill milk" and fight an additional boss; I used to enjoy the cat's New York accent immensely, and would indeed spill the milk every time I went in there to help someone just to hear the cat complain about... well... spilled milk :D.
Also, the fact that there was a New York mobster in Big Ben very much added to the amusement factor.
The voice-acting has now been replaced with someone's very approximate rendition of Cockney, which is... just... disappointing.
I am sure you can find an actual Cockney somewhere, or at least an actor who can do a proper rendition... Please help your young wizards ... :)
