This is why GOG.com is going to be the greatest thing to ever happen to PC gaming. I have seen this game going for 100 bucks or more on ebay in the past. It's a fantastic game that everyone should play, but who wants to have to pay 100 bucks in order to play it?
The space flight sim genre is all but dead. That's a shame. I think Freespace 2 is the pinnacle of the genre as far as gameplay goes. Wing Commander began to focus too much on storytelling and uninteractive movie sequences. Freespace 2 does away with all of that and instead, it gives you hours of tense combat. It's also very very pretty. Its visuals hold up very well for a 9 year old game. If the genre were still alive today, I wouldn't think any new games would look much better than Freespace 2.
