Fast and addictive; a great space shooter.
Freespace is fast, very very fast. And I mean both the in-game speed feeling, aswell as in display terms. I played it on my old system, a P200MMX w/Hercules Thriller gfx-card and 64MB memory, and it blew me away. Not only did the graphics display perfectly (without any noteable glitches), they were also very nice to look at. The AI is decent aswell, as in if you blow up a capital ship (a cruiser, for example), that ship won't be there to bother you again.
Another thing that I loved (after getting used to it), was the very simple yet elegant cockpit HUD-display. It gives you all the info you need, without cluttering the screen or reducing the size of your view-point. Rather refreshing, in this genre. On top of all this, Freespace comes with a very good and easy to use editor, allowing you to create your own missions in no time.
It takes time to get the hang of it, maybe a too much time for those not a fan of the genre.
The Bottom Line
If you're looking for fast and furious space-based action, I can heartily recommend this game.
