I really did like the demo, but I was only able to try it on my older PC 4-5 months ago. You should also mention in your review that you can usually pick up this title for 19.95 in most places.
I did -- right at the top ... where it says "Price"
The first level (same as the demo) is more a training mission and I much preferred the later missions, especially one in a factory complex, and one in a shelled-out town (where you can land in a church steeple and snipe to your heart's content).
Something I did neglect to add, is that once you've finished your core objectives, generally something new opens up -- maybe a new enemy comes in, or you have to storm a building. But it adds to the overall fun and longevity of the level.
