Overclockers Club published a review on the Ashes of the Singularity: Escalation
A quote from the article:
The easy question to answer right now is if Ashes of the Singularity: Escalation is worth getting if you do not already have a version of the game, and in my opinion, it is if you enjoy RTS games. It is fun and is doing many things right that make it very satisfying to play. Whether you should get it if you already have the original game is harder to answer, but I still think it is worth it. It builds on the original very well, and even though some of its features will be added to the original eventually, if you enjoyed the original, I think you will want to play this. Wait if you want, but I will still recommend it.Ashes of the Singularity: Escalation Review @ OCC
