Ok, I finished SAH a while back, and I'm currently in the middle of Homesick. And these campaigns are both excellent.
Currently, I like SAH better. Not that Homesick is bad, just that I like more action like in SAH than the focus on story in Homesick. Also, I don't mind flying a Loki for a while, but the entire campaign? Eh, I need more. Again, I'm not saying that I dislike Homesick in any way. It is a very excellent campaign, well made and fun.
SAH, this is just fun. I love it so much. You really get the feel that you're in a war, that you're a pilot in the navy. In FS1 and 2, I don't know. I just didn't get the feeling that I was in a war. The T-V war didn't last long in the first game, and fighting against the Shivans was just trying to survive. FS2 was kinda the same, but the NTF wasn't really a rival power. They were mostly organized rebels.
In this campaign, you're in a serious war. You fight off attacks of enemy armies, go and conquer bases and worlds of your enemies. It's just really fun. Plus I have never feared cruisers until this. XD Well, Great War era weaponry on them anyway. Beams overpowered the cruisers in my opinion.
It's just too bad I can't use all of the SCP goodies in SAH. As far as I know, the Inferno guys haven't released any shinemaps or updated thrusters yet. I think they did glowmaps though.
Anyway, extremely happy with these missions.
