Written by ME2 lead writer Mac Walters, it is true to the universe and characters, though a very superficial cast. I was surprised to see Miranda and Liara working together for the Illusive man, which explains their prickly reunion in the game proper. And here I thought it was just because I had romanced both of them.
Also gives a setup for how Liara becomes the Shadow Broker, and shows a side of Omega not seen in the games. All in all, it was a nice return to the universe after the games are played but the itch remains.
