A highly addictive game that it's more difficult than it appears.
Unfortunately I was too inexpert with this kind of games the first time I played it, so I simply could not pass the stages without cheating.
Fortunately I found this game in an old box and played a few months ago. I realised that my strategy wasn't appropriate, and searched the web for help. Google saved me --once again-- with a couple of websites that offered intelligent building structures in Excel format, and I finally could appreciate the beauty behind that programmer-minded game-motor.
I hope that gameplay gets some improvements in this brand-new 3D-version of the game. I am sure if they can do that, the game will be a success between mature strategy gamers.
