I just bought this game on eBay for my Retro-System (P3 with Voodoo-Cards and Win98^^) and playing it with a Voodoo 2-Card is just AWESOME!
Complex missions, "realistic" Space combat, good Story, not so bad graphics (a Voodoo gives a huge boost) make this game one of my Favorites.
I rate this Game a Must-Have for Fans of Space-Combat-Games and recommend to get the Sequel I-War 2 as well.
And 5,99$ are a very good price for such a great game. So, Get it!
