There's an old game, the name of which escapes me, can you lot help me?
It was a fully 3D RTS, first or third person (variable). In this game you built a base and units controlled by AI and commanded them. You could enter into any of these vehicles, however, and control them. It lacked a dedicated isometric view, but in the command center you could view the battlefield in the traditional way, but for the most part you were at the heart of the action. In alot of ways it was similar to Command & Conquer: Renegade (but predated it). There was a sequel as well.
Any help would be appreciated, my memories of it are kind of hazy, but I've got the premise down pat.
