This is a failed hex-and-turn-based strategy game.
In this game, I see so many points that have been poorly designed and they destroy a strategy game like this one.
For example, the Crusader self-propelled artillery (M109A6, although this weapon project was cancelled because of budget decrease) can shoot a target 4 hex away, whether before or after movement. Well that is considerable, as Crusader was designed to do things like that. But as the weapon range is not divided into anti-air and anti-ground, so its 7.62mm machinegun can shoot down a JSF patrolling 4 hex away, after moving a long distance to do a active attack.
In the mean time, Avenger Stinger missile Air-Defense can only shoot air targets 3 hex away, but its 12.7mm mg can also fire 3 hexes away, far than M1A2's 120mm main cannon. How can I accept that?
Strange things like that happen all the time. Without settings of fire priority cause the attacker is always get a huge advantage too much to affect the balance of the game; A badly damaged unit always does the same damage as a healthy one does, while with the attacker-wins rule list above, the game becomes boring; B-2 stealth bomber will be counter-attacked by a tank (and lost quite a amount of health) while throwing bombs, so why US government throwing billions of dollars to develop a stealth bomber and JDAM?
If you do like this kind of game, including units on hex; data of real-world weapon, from modern to WWII; turn-based and so on, I strongly suggest you forget games made by US or EURO corps--especially this one, the "Shattered Union"-- try Japanese. They really make such games good.
For the beginner of hex/turned based strategy games, I suggest a Japanese game called KAIKA NO GOUHOU, made by KOEI. Although it is somehow simple to a experienced player and still with some problems, it IS interesting.
First, you can use weapons from 6 countries, including US Marine, US Army and Air Force, Russia, German, England, and Japan.(actually, 5 countries), instead the same US weapon used by friend or foe in Shattered Unions.
Second, some feathers much more "Strategic", such as supply and replenish, ammo of weapons, etc.
Third, also using settings of army legion, KAIKA can use the whole legion into a attack or defense battle, instead of a disgusting reserve of troops settings. Why can I only use just a few units in a turn-based game while nowadays PC can support 20k units in real-time games? (Rome: Total war)
In fact, someone call Shattered Union is a American edition of KAIKA, and the former is too much bad.
At last, I had to say, judging from its contents, a 100MB or so should be able to put the whole game in, but it use 2CDs and cost 1.x G in the hard disk. I'm glad I used Anti-blaxx than buying it.
