Myth: The Fallen Lords from '98. My first MP game, other than MUDs. In some ways a precusor to the TW games, with a true 3D terrain engine, but far fewer units and each one controllable. Myth and Myth II are solid games if you see them in a bin somewhere, this is what Bungie did between Marathon and Halo.

I can't remember the name of it, but one of the early Earthsiege games where you moved your HERCs on a hex grid map. Probably better in memory than in actuality.
