I learned a lot while reading this enjoyable essay by Jimmy Maher.

Looked at today, however, Sherlock certainly wasn’t a bad note to go out on. Being built on the sturdy foundation of everything Infocom had learned about making text adventures to date, it’s not notably, obviously innovative, but, impressively given that it is a first-timer’s game, it evinces heaps of simple good craftsmanship. We may celebrate the occasional titles like A Mind Forever Voyaging and Trinity that aspire to the mantle of Literature, but the vast majority of Infocom’s works are, just like this one, sturdily constructed gamesfirst and foremost. Explore an interesting place, solve some satisfying puzzles — the core appeals of a good text adventure are eternal. And, hey, this one has the added bonus that it might just make you want to visit the real London. If you do, you’ll already have a notion where things are, thanks to Bob Bates, lifelong tour guide to worlds real and virtual. —The Digital Antiquarian
