Not even just that. I can't speak for Edinburgh, but in the area I live in in Glasgow we've had random fireworks go off during the day for weeks leading up to Guy Fawkes. One big explosion every now and then. One day, still bright out, I was walking home and almost hit the deck because one went off so close to me out of nowhere.
After Guy Fawkes it has been less frequent, but still happens, at very odd times. You can even check news and see that it's been an issue for a while. E.g.: https://www.bbc.co.uk/news/articles/c0j87zneq4vo
It stresses me out a bit, and I spend most of my time in my own home, with decent soundproofing. And I'm not a sensitive endangered animal.
Half Life 2 base now includes the Episodes and they have been delisted. The only thing in The Orange Box now really is Portal, since Lost Coast is also delisted and TF2 is free. Still a great deal tbh for one game, but you don't need it for basically any item in there.
