Doom the Way id Did: The Lost Episodes by various authors (review posted 08/31/19)
Doom the Way id Did had the community in a fervor, attempting to make levels in the styles of Romero, Hall, and Petersen. Many of the castoffs were collected into this megaWAD. It's full of classically-oriented action with a few twists here and there as things diverge from "id-like" design. Its infamous post-production period got it a Mordeth Award as well as a few new definitely-not-id outings.
