Tempest Rising is always going to be compared to Command and Conquer. It's set in the '90s, Frank Klepacki does the music, and there are two campaigns where you play as two different factions. Even the finer details, like the talking head cutscenes, and the fact that the Tempest itself is an energy-rich, alien-esque crystal, just like Tiberium - I can imagine the pitch meeting where somebody said 'Westwood and EA aren't making Command and Conquer anymore, so we're going to do it'. But Slipgate's RTS game is way more than an homage; it's not just Command and Conquer for a post Command and Conquer world. Available to play right now, Tempest Rising has the potential to rise higher than its influences.
