jigglywiggly: I also want to say a big "thanks" to qwerty0 for that great subtitle file. Another great thing is that even until now, it is still available. I tend not to play English versions (intentionally, to help force myself to practice other languages), but still this may be a big help when I get stuck. It must have taken a fair bit of work, thank you.
By the way, are you still missing English lines (like for George Abbot as you mentioned)? If you are still around on the site here, perhaps I can help. That character has a very pronounced, difficult accent but as far as I remember, I don't think there were any lines that I couldn't catch when I played through the game many years ago (sadly enough I am very used to difficult UK accents and can understand most of them by now ;) ). But anyway it would have to be soon, if you are still here (I have been logging in occasionally lately but perhaps that may not be the case for much longer, when other real-life tasks start pressing again...)
if ur serious about properly enjoying this gem of a game (or any other for that matter) I'd avoid any subs made by my dear compatriots like plague. Obv i've never seen these particular ones, just speaking from experience.
