Unity of Command is a simplified strategic turn-based look into the eastern fronit during WW2 - similar in many ways to the classic Panzer General, while adding some fresh ideas of its own (such as the concept of supply, which enables increasingly realistic maneuverig in the spirit of the historical blitzkrieg. Having said that, the game also suffers somewhat from oversimplification, repetitiveness and rigidity. When considering buying the game, consider:
-Easy to get into, yet challenging enough to try and master
-Some tactical planning and thinking required, luck and chance is involved so there is some variety in gameplay.
-Quite immersive, the total seems more than the sum of its parts.
-The AI seems quite simple: you make a certain set of moves and it always reacts similarly.
-Unrealistic winning objectives - sacrifice your army simply to gain possession of a few winning hexes for one turn and you suddenly have "won"?
-No air units available
-Only scenarios where offensive is to be taken (AI lacks the ability to launch a coherent offensive?) - some defensive scenarios would be welcome
-"Brilliant victories" often depend on chance (e.g., chancing in-game weather), yet proceeding in the campaign in some cases requires such victories - the game therefore makes you grind several scenarios over and over again.
-The scenarios always start the same - some alterate starting positions would be welcome for variety.
-After you win the campaign, there's a smiple "Campaign completed" message and nothing else - really?
-Music can get repetitive and the graphics are not the selling point of the game.
Overall, I tend to recommend the game for people interested in the topic and looking for some easy-to-get-into strategy gaming - not at the level of Metacritic (average 84/100), but rather at the level of the user reviews (7.2/10).
In other words, it's quite ok.
