Based on the spreadsheet values, I like this change a lot. It keeps a similar EU/t per reactor but adds complexity and new ways to gain PLE materials. 👍 |

Do you plan to balance the EU/t available via the Extreme HX -> XL SC turbine route in a similar fashion? It doesn't look like this PR makes any changes to the quantities of SC steam produced by these plasmas, and some back-of-the-envelope maths -- sorry, i don't have a nice spreadsheet like @S4mpsa ;-) -- shows that there is very little value in going past Runite, or even Astral Titanium, when going that route. For example, to replace my 2x T3 fusion kicking out tin plasma to generate 6,144,000 L/s SC steam for an XL turbine with 16 cosmic neutronium rotors, I need 720L/s of Astral Titanium (roughly 0.57 T3 reactors), 585L/s of Runite (0.47 T3) or 570L/s Celestial Tungsten (0.45 T3). Given the huge jump in plasma energy from Runite to Celestial Tungsten, it seems like something is off here. The XL SC turbine will kick out ~75.2M EU/t or ~1.5B EU/s so we can calculate the efficiency multiplier of this path v.s. a an XL plasma turbine. (2.45 is rotor efficiency) 720L Astral Titanium = 204.96M EU * 2.45 = 502M so efficiency multiplier of SC route = ~3x Assuming the efficiency gain from runite / astral titanium through the extreme HX is the desired balance, the HX should need ~285L/s of CT plasma. Or, 1500L of CT plasma should kick out ~32.4M L of SC steam per second instead of 16.2M L. Or (argh) you could nerf the efficiency gain of the HX to make CT plasma look better. More directly: 1500L CT plasma = 16.2M L SC = 1.08B EU = 66.66 EU/L So I assume that 33.33 EU/L was the balance point previously and these changes in EU/L just need to be reflected in the SC numbers? |

Ah, I found why celestial tungsten is getting limited, at least: 720,000 * 1500 * 160 = 3.24B which is > 2^31 But plasmas don't ever create superheated steam, they always output supercritical. So perhaps we could set the SH steam value to 0 and remove this check? If that sounds OK I can send a PR for it. That code also explains the weird tin numbers -- I missed that tin uses 1000 plasma to generate 4.5M L SC steam, not 1500. So that's fine, it's just celestial tungsten that's broken. |

I have not tested the plasma output through SC turbines, because those have been problematic for a while and have multiple bugs that could lead to even more ridiculous plasma setups. The more people use them, and the more plasma-related content is added, the more issues I see coming up, and I honestly have never found how to properly support these turbines. That said, the PRs related to this have been approved. Maybe complete fixes will be made in time. |
See #651 for the PR that introduced these plasma chains. Big thanks to @S4mpsa for making the spreadsheet and helping me decide how these chains should be balanced to be useful, yet not too strong.

This is the spreadsheet Sampsa made, with a general overview of the numbers involved in this PR.
What's the objective?
These plasma chains are meant to replace the Helium/Tin Plasma spam that has since been heavily nerfed when used together with XL Plasma Turbines, which was the usual setup. The final powergen numbers are somewhat similar to what Helium Plasma could do with compacts before, but the setup is a lot more extensive and more materials are needed to automate the chain. Hopefully, this amount of power will be enough to sustain a base until Dyson, but it won't be anywhere as simple as how fusion has been until the nerfs.
What are the fusion chains like?
There are three chains, one for mk1 reactors, another for mk2 and the last for mk3. Each chain needs the final plasma of the previous one to be made. The focal point for compact reactors and XL turbines is the mk3 chain, which is the one that can match the previous powergen's numbers, but with a lot more complexity. The other two chains aren't as relevant for this stage, but they are both more powerful per fusion reactor than the 1-recipe setups of Helium and Tin Plasma, with an added cost like everything else.
What would a compact reactor setup look like?
The final recipe that makes the strongest plasma, Celestial Tungsten Plasma, is the slowest recipe, so it's the only one that needs to be a compact. However, other recipes might also be moved to compacts because they might only be 6x as fast, which would force a number of normal reactors. The entire mk3 chain, which includes the other two, starts from Helium Plasma and requires 14 new fusion steps to be completed, but the power per reactor is considerably higher if there are no bottlenecks before the final recipe. The complete setup would require a good number of reactors either way, but the added complexity and the choice of which chain to build between the three should add more entertainment and choice possibilities to the player, rather than simply choosing between Helium or Tin Plasma spam.
Other notes:
Celestial Tungsten Plasma's fuel value was buffed to 720M in order to improve the EU per reactor by more than 4x the mk2 equivalent, to account for the 4x difference in EU per amp across tiers. Additionally, this new fuel value avoids penalties even in the spacetime turbines.
