Wanted to thank Templars once more for all the help he gave, and continues to give. It's a fine game, if not somewhat addictive. I recommend, if you haven't tried it, to give it a shot. I was slow at it at first, but have picked it up rather quickly. It's also rather interesting, in that, like BlueMax, bigger isn't always better or more fun. Sometimes, the little Destroyers, and Frigates are every bit as fun as the larger stuff. (Though, I admit, I have only been able to get a Light Cruiser as my largest ship so far.)
Unlike BlueMax, where every game pretty well stands alone, Navy Fields allows you to grow, and your victories mean something. In order to get the next larger ship, you need to grow in experience. The more you win, the faster you grow. You still gain experience if you lose, but winning is higher experience, as well as a better payoff. Which leads again to bigger and badder (I know, it's not a word) stuff!

Give it a shot.
If you need help, contact Templars or even myself.
