I got the game when it was on an 80% sale for $2. At that price, it's worth it. Anymore... I dunno.
I didn't experience any glitches in the game, so I dunno what others are talking about.
However, the game still really isn't that great. The concept seems awesome, but it's a big letdown. The game is very simple and repetitive. You buy spies, assassins, and political advisors over and over to influence smaller countries before bigger countries to get the domino effect, and focus on countries that are rich in income and natural resources. The tech, resource, and military advisors are situation specific. Space race? Forget it. Nuke research? Forget it. Just zero them out and pour all your research into spy tech. Lose a spy from an assassination or revolution gone wrong? Buy two more to replace it. Heck, buy four more so you can train them in advance. Also, buy finance, tech, and resource advisors to boost your economy where it counts too.
What really stinks is the in game spreadsheet of all your spies doesn't hone in where agents are located if you click on their row. In other words, you have to remember where your hundreds of agents are on the board. If any go passive from completing a mission, but you forget about them, you'll be stuck paying upkeep for nothing for the rest of the game.
The game does give you a master plan button that automatically executes missions if they're successful within a certain probability, but still, you're just doing the same thing over and over again. The hardest part of the game is upkeep since agents cost $15k per turn in the field. You'll buy a bunch of agents since you have so much to do, but then you won't be able to afford more towards the game's end where you're mopping countries up. I guess the capitalist campaign was easier since you didn't have to do as much of this though, and you already start with the Middle East which gives you a boatload of resources. As the commies, I just influenced Iran, Iraq, Saudis, then Argentina and Brazil at the same time that I mopped up the Middle East. Then I took Japan, Pakistan, Thailand, Norway, Finland, France, Mexico, Italy, Britain, South Africa, Indonesia, Australia, and Canada. The computer took Poland, Czechoslavkia, Hungary, Vietnam, Angola, Republic of Congo, Rwanda, and Laos from me, but who cares? I even got spontaneous revolts in Greece, Turkey, Algeria, Peru, Bolivia, Burma, Malaysia, Mozambique, and Chile.
I dunno... I beat the game by 1970 both as capitalists and communists. It just wasn't that much of a challenge even if it's harder to take Belgium than Britain. South Korea and West Germany are a pain in the butt to influence also. China's a pain in the butt to take as Capitalists, but you just have to surround it with capitalist countries and let the domino effect work out. The communists don't start with many lands, so it's all about picking them off one by one until the Soviet Union and China are all that's left standing. When the computer spies on your homeland too, all you have to do is assassinate its agents one by one every game month. That kills its treasury very fast since it has to train skilled spies over and over. Without spies, Canada stops flip flopping too since assassins can kill the Pope and Kissinger so Che can get down to business.
The computer tried to kill me with Chernobyl in 1967, but did that work? Nope. This would be GREAT as a multiplayer game, but there's no option.
