Costs of LRTs: How they interact with PRTs and other LRTs

By Nachtergal Phillipe ( nachterg@student.fsa.ucl.ac.be)

All tests were made starting with the "standard" humanoids.


Costs for all the lrts were (if only 1 is checked) as this :

IFE -78 NRSE 53
TT -140 CE 80
ARM -53 OBRM 85
ISB -67 NAS 95 (JOAT only)
GR 13 LSP 60
UR -80 BET 23
MA -51 UR 10

Advantages have negative costs. Disadvantages positive costs.

For the rest of this article, only the sign counts; whether or not the cost is close to 0 is irrelevant. ( resistance is futile ;) )

The only one that differed when changing PRT was NAS.

NAS Standard cost is 108
JOAT: 95
SS : 41
PP : 15

All others never varied by more than +- 1

Now, back to the standard JOAT Humanoids: what happens if Icheck more than one LRT?

Soon enough, you lose extra points for checking many LRTs.

Making a complete analysis, two clear factors showed:

  1. The number of LRTs checked
  2. The difference between the number of Advantages checked and the number of disadvantages checked.

Both factors are cumulative.

Here are complete results:

Cost for LRTs
0 to 4 LRTs 0
5 LRTs -17
6 LRTs -40
7 LRTs -70
8 LRTs -107
9 LRTs -151
10 LRTs -201
11 LRTs forget it
Costs for advantages v. disadvantages
#adv = #dis 0
#adv = #dis +/- 1 0
#adv = #dis +/- 2 0
#adv = #dis +/- 3 0
#adv = #dis + 4 -14
#adv = #dis - 4 -20
#adv = #dis + 5 -27
#adv = #dis - 5 -40

So for exemple,if you check 5 advantages and 1 disadvantage, you'll pay 40+14=54 points more than you would have thought.

The only situation I've found where you gain a few extra points for checking a additionnal LRT is if you already have 4 disadv. and no disadvantage (-20) and choose to pick an advantage: you end at -17 (gain of 3). (you still have to pay the standard cost for that new advantage).

Cost of TT also depends a LOT on your Habitat settings (both hab range and pop growth). No other LRT does.

I haven't seen any connection between costs of LRTs and mine/factory/tech settings but I haven't thoroughly tested that.

That's all for now.
