We got to interesting places we would've skipped if they weren't in the puzzles. The "Shadow of the Prism" is very well put together, with good, challenging puzzles, a nice plot and fine but kinda predictable characters. It is quite a lot to read though and the tour doesn't really take you the main city centre. Anyway, whether you are a tourist or you want another perspective on a city you already knowl, this is a must-do to enjoy half a day!
