the reason i give this three stars is for the expansion. I am going to be very clear about this. The expansion SUCKS! as for the main freespace campaign, its good but not as good as Freespace 2. The last level is a bit over the top in my opinion and the difficulty was too high on normal ( i dont like playing on easy). So i give the main campaign a 4/5 while i give the expansion a -4.5 out of 5 (notice the negative symbol). For 6 dollars this game is definitely worth it.
