An excellent game in the 'Tycoon' format. Challenging and fun.
The basic game comes with two missions - the Adventure story and the War Story. The Adventure story has 14 levels, with the first 5 basically teaching you the concepts of the game. And then the fun of resource management begins. Only time is your enemy as you try to accomplish the various goals of each level. With only a couple of exceptions, the levels are all doable on the first try, but the real challenge comes in trying for the reward of gold medals for finishing levels by a certain time. If you're like me and enjoy this type of game, this is all the incentive you need for hours of fun. And some of the levels are downright tough when you least expect them.
The War story introduces the concept of military defenses as you build your space stations in hostile territory. The gradual build up leads to a spectacular showdown that will require lots of guns. While this story certainly has its thrills, its not as tough as the Adventure. There's also a couple of scenarios and sandbox games that let you play to your heart's content, even when you've satisfied your appetite in the two stories.
The graphics are decent and the sounds/music average. At the same time they don't distract from the gameplay which is easy to master; the thrill of the game is in the strategies you think up to accomplish the goal(s). You get a lot more here for $10 than you'd expect. So, if you're up to the challenge, give it a go for yourself...
