Okay, I want to discuss the cost of some of the aircrafts, because I think, they are a little bit too expensive, but maybe, this is intended.
I think the requirement "alien materials" for some ships is a little bit too high and the only "bottleneck" I have, when building those aircrafts. The alien ship I get the most alien material out of it is in my opinion a 100% harvester. One 100% harvester = 800 alien materials. Good. So let's look at the cost for the aircrafts and how many harvester I need for it (AM = Alien Materials, H = Harvester):
- Dragon Interceptor: 5000 AM (6.25 H)
- Starchaser-class Interceptor: 7000 AM (8.75 H)
- Stingray Interceptor: 9000 AM (11.25 H)
- Raptor-class Combat Transport 12000 AM (15 H)
Well, the other requirements like money, time to build and these alien ship things are laughable compared to the rest, because I will have 10x of these requirements, before I meet the alien material requirement. I'm playing on easier and it took me about 1 1/2 ingame months to get those 15 harvesters for my Raptor and only for one. My problem was not to disassemble them (I have at least 3 bases for that), my problem is, that I need 15 harvesters and I don't get that many missions with harvesters, so I need to wait until those missions pop up. So I was able to get the best interceptor and the best drop ship, but only for one base. And I dunno, but the cost for the Dragon and Starchaser is so high compared to the Stingray, I don't even consider them to be build.
I think, the alien material cost is too high and I would do it more like 2000, 4000, 7000, 8000 for example. It still takes time to get the alien material, but not that much and if you're impatient, you could at least build a smaller interceptor.
Again, this is only my opinion, maybe the high cost is intended, but it doesn't feel right when playing the campaign.
So... discuss!
