I understand that you want more specificity, but it's simply untrue that the page doesn't make clear generally what sort of project it is.
Here's some more depth in my own words. It's a real-time strategy game from Cave Dog Games in 1997. It's a precursor to Total Annihilation: Kingdoms. It's a spiritual ancestor to Spring, Supreme Commander, Supreme Commander: Forged Alliance, Supreme Commander 2, the Forged Alliance Forever project, Planetary Alliance, and a few others. Zero-K and BAR are other updated reimplementations. It competes in the space with the original Starcraft, with Warcraft II, the earlier Command and Conquer series games, Dune 2000, and that sort. It has land, sea, and air units and dedicated construction vehicles of all three types. By default there's a commander to protect whose death causes a player to lose the game, but that can be configured to be off. There are stationary units like artillery and buildings including power generators, metal extractors, and factories that make the other units. The construction mobile units and the commander build the land units and buildings. The linked page shows the sort of graphics the original has and puts them side by side with the reimplemented version from the project.
It ran on Windows 95, 98, ME, and XP just fine. ISTM it would run on NT 4 and 2000. I think it runs on 7 from the CD and maybe 10. I don't use the discs much these days though because despite owning two or three disc copies I also got it on sale on two or three different digital storefronts.
