Bruce Geryk at GameSpy has written the first part of a two-part series on the history of Real Time Strategy games. It covers 1989-1998, and lists the Myth series as one of the early fruits of RTS evolution . The banner graphic for the series even has a charging Zerk on the left hand side.

Myth only gets one paragraph on that page, but the praise is lavish:

The focus on unit tactics required some improvements to the standard interface of the time and the ability to manage formations (with unit placement being of the utmost importance). Myth also introduced some interesting multiplayer games, like Last Man on the Hill. With its outstanding graphics, smooth multiplayer, and tactical gameplay, Myth and its sequel, Myth II, carved out a niche in the real-time market for those more interested in combat than in resource gathering.

There's not much more Myth-related content there, but the series itself is an interesting read.
