This is game is an amazing RTS set at the very end of the Cold War. I can't say too much due to spoilers but it has great story line, you actually feel for all the characters in the game, and as an actual war veteran (Battle of Fallujah in 04/05) I can say it was a great experience. I had it on Steam a long time ago and loved it, but it would not play ever again so I was extremely excited seeing it in GOG and patched. Save often, even right before an ending of a mission since it can crash. There are actually no bugs or glitches in the game so as long as the game runs, it runs great but you may have a crash unexpectedly (this is why you save often) and just load it back up, it may not be for everyone though since I had other things running in the background while I played. The air and artillery support in this game is awesome, but the story alone is worth it, the voice acting as well was great and kept you in the moment.
Since there are so very few Vietnam games let alone an RTS, this is a fun Vietnam game. I will not say it is a great Men of War game though, in that it is the fraction of the size of of Men of War. There are no full scale or even half scale battles in the game. You only command a squad of soldiers at any given time and you are mostly sneaking around. I had fun and was entrained but was very sad when there was no full scale battle, especially when they bring in the helicopters.
