The article's timeline ends in '96, two years before the release of Starcraft.

I think it's more about the origin of the genre rather than it's greatest exponents. I believe an honest retrospective on RTS should also include Warcraft 3, RA2, AoE2 (!) and Cannon Fodder, among many other titles.

I share your sentiment about Stormgate, I hope I get to play it without having to upgrade my PC, at least.
