But while other developers have been keen to expand on the theme, adding everything from 3D graphics to first-person perspectives, Westwood has always remained true to its retro roots. It's a simple formula, and a much-imitated one. Somewhere else on the battlefield your opponent is doing the same. A few units and a battlefield with scattered resource fields at your disposal, you build a base, harvest these resources, and use funds thus gained to construct an army. Command & Conquer games, in the past, have followed the same recipe. Westwood isn't exactly a name people associate with innovation.
