Balance of Power is an oldie but a goodie. In it, you take control of one of the two superpowers of the Cold War, the USSR and the US. In it, you are faced with the prospect of nuclear winter, and of the opposing side gaining a monopoly on power. You have some spheres of influence, and you must operate with the utmost caution, and try to slowly, gradually wear away at the other superpower's spheres of influence until there is nothing left to wear away at.
Controls are nothing special, arrow keys and enter, and graphics are bland, especially in this day and age.
However, the meat of the game is the game-play. The difficulty levels range massively, and they not only make the other side of the Iron Curtain harder to beat, but also toss in a slew of new factors and actions into the meddle. From Finlandization (Finland was a staunch ant-communist force in the Baltic, and in WWII it managed to preserve its Capitalistic Democracy against both attacks from Hitler and From Stalin, but as the Cold War's peace treaties left Finland isolated and alone with the Russian bear, it was forced to take a inoffensive role to Moscow) to Aid to Rebels, there are
many, many, many things to deal with. And you will have to deal with ALL of them.
Fortunately, in your quest to save the World (or to conquer it) you are not alone. Due to complaints from the previous version of Balance of Power, a decision was made to include some "advisors" who serve no specialized purpose, but to give general advice, namely, how they believe the chances of an action you are thinking of undertaking. The responses range from "They Are out of line" to "They will ream us for sure." on various issues. BEWARE. The Advisors often have differences of opinions on cases where the "issue is in doubt" and thus you must proceed with caution.
Ultimately, it will attract few outside the genre, but for those who love brinkmanship, this is for you.
