Do you recall any other details? Have you eliminated “well-known” games? I ask these questions because I really like helping people find forgotten things and want to help you find the game (assuming you want to find it).

I totally agree about Dawn of War, but I’d place soulstorm as peak solely because of the mods being so good (and adding two of my favorote factions). I liked DoW2, but a 40k RTS with apocalypse scale armies would have been a cooler direction to take the franchise imo. Hence the love for soulstorm modding.
