Hi, thanks for stopping by and sorry the game is unlikely to run on your laptop. I live in Edinburgh, Scotland so that's why it rains all the time in the game XD, but probably quite similar in terms of gothic architecture to Prague. I've never been but I know Bloodborne's team took a lot from the city! It was also infulenced by Bram Stoker's Dracula (the 90s film), the comedy Young Frankenstein and the stories around the violinist Niccolò Paganini selling his soul to the devil.
I've not played a Call of Duty game since the first one in the early 2000s, but I think I know what you mean and that's very kind of you to say.
