THE YEARS BEFORE WARP 10
The previous segment was mainly about the Expansion Era, and highlighted many reasons why taking IFE is so important during that era. The next segment will deal with the Warp 10 Era. But between expansion and warp 10, there is another era that I will refer to as the Early War Era. And that’s what this segment will cover.

IFE but not NRSE vs. IFE and NRSE
In Hardheads, at least five out of the ten non-AI races took IFE, but not NRSE. Is it worth it to have IFE but not NRSE? Let us find out.

First, what are the differences between a race that takes IFE and NRSE, versus the one that just takes IFE? What sort of impact does the NRSE choice have on early warfighting?

Facts on Engines
The NRSE race will have less engines available for warfighting. The QJ5 and LH6 will both be available, but neither those engines is faster than the FM and the race already paid points for IFE, so why would it bother building them? So for warfighting, the NRSE race gets to choose from:
Fuel Mizer, available at prop 2.
8 I, 0 B, 0 G, 11 R. Battle speed 6, mass 6.

Daddy Long Legs 7, available at P 5.
11 I, 0 B, 3 G, 12 R. Speed 7, mass 13.

Alpha Drive 8, available at P 7.
16 I, 0 B, 3 G, 28 R. Speed 8, mass 17.

Trans Galactic Drive, available at P 9.
I 20, B 20, G 9, R 50. Speed 9, mass 25.

In comparison, the IFE only race gets to choose from all those engines, plus:
Radiating Hydro Ram Scoop, available at P 6 N 2.
I 3, B 2, G 9, R 8. Speed 6, mass 10.

Sub-Galactic Fuel Scoop, available at P 8 N 2.
I 4, B 4, G 7, R 12. Speed 7, mass 20.

Trans-Galactic Fuel Scoop, available at P 9 N 3.
I 5, B 4, G 12, R 18. Speed 8, mass 19.

Trans-Galactic Super Scoop, available at P 12 N 4.
I 6, B 4, G 16, R 24. Speed 9, mass 18.

Why Not Just Use FM for Warfighting?
Now, since both races took IFE, they could just use the FM for all their warships. The engine costs 0 G so it’s great for +f races. It’s also very efficient at warp 8 and 9, so long distance travel is no problem--. It only costs 11 resources at prop 2, which is less than any other engine here except the RHRS. It takes 2 levels in prop, which is far less levels than any other engine. And it only weighs 6kt, which is less than any other engine here. From those points of view, one might wonder why every race doesn’t go with NRSE and just use the FM for all their warships. However, there are other things to consider in this era.

RHRS vs. FM
For –f races, Iron can sometimes be a limiting factor (not as much as Germ is for +f’s though), and the FM costs more Iron than any other ramscoop shown. But on the other hand, the other ramscoops will all take many more resources to build than the FM, due to the listed cost and especially because of the research costs. The RHRS is the only scoop that shows a cost lower than the FM. If a prop cheap race researched it the cost would be about 745 resources, depending on other research priorities. It would then need to build 248 RHRS’s before it broke even with the race that just built the FM’s from the start, which could have built 67 FM’s during the same time period the RHRS race is doing research, which might amount to 20 Frigates or maybe 5 Cruisers. Besides that, once the race that researched RHRS finished, it would find that the FM’s price had miniaturized to only 9 resources, while the RHRS stayed at 8. Building those less fuel efficient and heavier RHRS’s would suddenly look a lot less attractive. The RHRS could also be a liability if the race’s radiation hab midpoint isn’t at least 85, since grouping it with any colonists will end up killing some every year, resulting in further costs. Shooting for any of the ramscoops for their low Iron cost would cost far, far more resources than just sticking with the FM, and they’d all be a lot heavier. While early on Iron can be a limit for –f’s, resources seem to be an even bigger limit. Unless a –f (like an AR) encountered an incredible shortage of Iron, building FM’s would almost certainly be much better than going
...




Yeah, bread too.
