**** 4 out of 5 stars in my opinion.
Yes, I really enjoyed playing this game. Graphics, for 2009, are quite good, explosions are well done, and it is played in real-time. Artificial Intelligence (AI) is smart, but can be overcome as it tends to repeat most of its moves at each mission restart (predictability). But, you will be CHALLENGED to get through some of the missions and strategy will be required as the enemy will change its strategy in ways that you may not expect. The AI will provide some "surprises" which makes it entertaining. It will keep you alert (situation awareness) and busy planning your strategy. I found it to be quite ENGAGING and felt determined to finish it - and did. It has been 5 years since I played it, but I remember it as one of my favorites in this genre. Try the DEMO and decide.
