No, Freespace 2 IS the best space sim out there. Not without its flaws, and far from being a perfect game because it's a genre that simply hasn't advanced since the era in which it was made.
Spore is not the game we were expecting, but not bad for that.
A few expansions down the line when it becomes more like its original vision and it might be a good game rather than just an enjoyable one.
I wouldn't care except that the Starforce protection on my old copy of 'Soldiers' is causing it to crash on my old computer, making LAN games of it impossible.
With any luck the GOG version of the game will fix this issue.
