When I saw this had become available on Steam, I was overjoyed. Freespace: The Great War was one of my absolute favorite games as a child, and I believe it still holds up strongly to this day.
The game begins 14 years into the war between the Terrans and Vasudans, and before long, an even greater threat shows its face, an ancient and destructive alien race known only as the Shivans...enemy to Terran and Vasudan alike.
Freespace: The Great War is a space flight sim. While most missions involve you either protecting an important target, or wiping out enemy forces, oftentimes both, they are all varied in their actual content and no two missions really feel the same. As the game progresses, you gain access to a good variety of different ships, each with varying strengths and weaknesses, as well as an assortment of different weapons.
Another of Freespace's strong points is its atmosphere, formed mostly from the music and dialogue. It will make you feel like you ARE the pilot, and a part of the game itself. This is definitely one of the things that helps to set Freespace apart from other space sims. I have never played another space sim that gave quite the same feeling Freespace does.
This release includes the expansion, Silent Threat, which continues the story after the main campaign's ending with several additional missions.
I really can't recommend this game enough. If you're a fan space flight sims or flight sims in general, and have not played this game, now's your chance to experience a masterpiece.
