Yeah, fantastic that you do those features, but "Essentially, Sacrifice was a 3D real-time strategy game before 3D real-time strategy games existed." is not correct, as has been noted.
Battlezone, Dungeon Keeper and Myth were out in 97, Myth II, Warhammer: Dark Omen and Wargasm in 98, Machines, Populous 3, Homeworld, Warzone 2100 and Shadow Company in 99. Surely there are more, as well.
Sacrifice was out in 2000.
Ground Control's another that comes to mind as well.
