buying this game, you get a great war time story from the perspective of an anonymous pilot. also, you get access to a great many mods and campaigns for Freespace 2 Open(available free from hard-light.net), an open source engine upgrade project greatly enhancing the visuals and capabilities of the base Freespace 2 game. note that these mods still require access to the Freespace 2 data files. d the foremost of these, in my mind, is the blue planet series. BP carries on the freespace story with a shockingly good narrative. buy it, you wont be disappointed (unless you don't like flight sims)
