Both games feature a «Commander» unit, a giant mecha, which uses atomic - level manufacturing to build an entire economy on far - off planets literally from the ground up, which is an interesting inversion on how mecha usually are used in games: the «Commander» is more or less the player character, and while their large mecha is by no means weak, it's a central unit because of its production capabilities, and not because of its
arsenal, which as a mecha fan I always thought was a nice way to work the idea of a «hero mecha» into an RTS, because you can relate to the Commander mecha's role as, well, a Commander on the battlefield
rather than as simply a
powerful named «hero» unit as exist in most other RTSes.
