I've been playing C&C: Red Alert ever since it was released, and if you love that game, then you will love this.
There is a bit of a learning curve strategy wise, and the developers have stressed that it's not a "whoever can click fastest wins" type game, and rightly so. For example, ships are not destroyed in seconds, it's more like minutes. You must develop your own strategy, choose your upgrades wisely, and develop your planets sensibly.
The research options are very extensive, and although I've only been playing the game a few days I am already paying the consequences for being greedy getting every new technology when it becomes available. This is not how to win the game.
The only negative side to this game is the fact that it will take a huge chunk out of your social life, so if you're reading this you've been warned!
