The thing about missiles is they take up a lot of space. Sure, a 6-MSP missile is just 15 tons, but you'll need a few of them for a salvo (and quite a few—or larger—missiles to get through point defense), and they all add up as you add more volleys. The new system essentially nerfs the box launcher spam so now you'll need either larger or more expensive missiles, or have other weapons onboard as well.
I've only had one battle in the new version. A single raider, I think? An approximately 7-ton ship going about 5 km/s. Sensors indicated possible cloaking and thermal reduction. Not enough data to form an opinion on the new combat.
In any case, our home system got fucked by RNGesus. The mineral deposits are shit, with little to no corundium and mercassium, and Uranus is the only gas giant with sorium (thankfully 59 million tons at 0.7 accessibility). Europa is the only colonizable body with minerals on it, all others are relegated to wealth creation. I wasn't about to try and reach the 100+ bkm asteroids to check for any wunderdeposits, so we tried to colonize other systems.
Jump points one and two are frightfully in the inner system—one is basically on the orbit of Mars. Jump point three is on the orbit of Saturn. A bit too close for comfort.
The first system we reached, Khalkfontein, looked promising as it has amongst others a single low-cost body but it also has Precursors (I think).
The second system, Kalizwali, is empty. It has two branches. One is a series of empty systems that leads to Telantha, another promising system, but it's 8.5 bkm away and we've spotted raiders there. The other branch immediately leads to Mhaladan, which immediately branches to Dynghaz and empty Wancandhu.
Mhaladan (9.5 bkm away) has three colonizable planets, all of which have a colony cost greater than ten. Mhaladan I has one low gravity moon, and Mhaladan III is a Venusian hothouse and is the only body with any minerals, mostly Neutronium, but with geosurvey potential.
Dynghaz (15.4 bkm away) has three planets, all high cost, and many low gravity asteroids. Dynghaz I is Venusian, naturally. Dynghaz II is a sorium gas giant, with many moons, six of which have acceptable gravity. The 19th moon has over a million tons of 0.9-accessible corundium and has acceptable gravity, so that's nice, though there's some frozen methane that will need to be removed. Dynghaz III is an unsurveyed gas giant with many moons as well, three of which have acceptable gravity.
The third system, Rigel, has a single gas giant with some sorium, yay. Beyond it lies Andaloa and Lhadalan (and empty Zayanofar beyond that), both of which are claimed by the NPR.
It looks like early colonization of Mhaladan and Dynghaz is on the books, as is an early war with the Precursors in Khalkfontein.
In other news, I've finally re-researched the ground units. Gotta get those specializations in. The unit series system is still a mess. I don't know why Steve doesn't let us reorder the series. It's going to look chaotic if you don't plan ahead for all the unit series you will possibly have. May you be granted mercy if you have OCD.
I had a go at the new missile design. I actually have a 3.2-MSP AMM now, with four 0.6-strength warheads and retargeting capability. It should take out a 12-MSP missile and not have to worry too much about decoys. I have a 2-MSP 4-strength anti-fighter missile with terminal guidance; a 6-MSP 9-strength mainline ASM with ECCM, terminal guidance, and two decoys; and a 12-MSP 25-strength anti-capital ship missile with the same package as previous. The anti-fighter missiles, while standard, worked well against the lone raider.
I've also tried to design a cruiser, both regular and jump variants. The same problem persists: it's a 40-kton rust bucket that's breaking at the seams. I don't even think it's feature creep. The jump cruiser is so barebones it ought to be a light jump cruiser. It doesn't even have a medium range weapon like a laser. Even if I removed the shield, that's still only a thousand tons shaved. I could also maybe shave another thousand tons or so by not using box launchers for the ASMs at the cost of reduced salvo size. I can only conclude that cruisers in Aurora are just behemoths by nature, at least in the early game.
