I feel random pauses could become annoying if long turn calculations (in mid- and end-game phases) will disappear.
Otherwise, no, they could be acceptable.
Please, an explanation and a question about post-start multi-system NPR.
Requested explanation: If we want large multisystem empire(s) at start, we set non zero values for at least one of NPR Base Explored Transits, NPR Random Explored Transits and NPR Max Start Systems parameters.
But this new addiction will also cause generation of post-start multi-system NPRs. So, I understand that we will never again meet single system NPRs, apart minor races: is it correct?
Question: how many systems will each post-start NPR control/know?
If you set all the parameters to zero, you will have single-system NPRs. If you set either the Base Explored or Random Explored to a positive number, you will have multi-system NPRs. The Minor Race option is checked first during race generation, so if you set that parameter, you will still have minor races with one system in a game with otherwise multi-system NPRs.
You can change the parameters at any time, so you could generate multi-system NPRs at start and then just set everything to zero.
If you want some small NPRs and some large, leave the Base at zero and only use Random.
The number of systems per NPR will depend on a combination of the parameter settings and the systems generation. For example, if you set Base to 5 and Random to zero, an NPR will do five rounds of outward jump point exploration. It might only have a few systems. It might find a hundred or more. The Max Systems option is for you to control that upper number if desired.
