I just got my copy of Conquests, and finished some tests to see if anything related to corruption has changed. Did it ever!
Let us pray for a patch now...
- FP rank bug is fixed. Cities closer to the FP than to the Palace no longer use the Palace's set of cities to determine OCN corruption.
- There is now a penalty instead of a bonus for RCP. They 'fixed' RCP by giving equidistant cities the worst rank, instead of the best, as was the case in PTW. So now you get penalized for building two or more cities the same distance from the Palace or FP. Note that distances are still rounded down, so a city at distance 4 is considered the same distance as a city at 4.5, and they would get penalized for their RCP positioning.
- The FP increases the rank of all your cities. More specifically, when you build a FP far from your capital, all cities near your capital have their corruption increased because the rank of all cities is increased to 2(r-1), where r is their old rank without the FP. So building a FP may or may not increase your overall corruption, because you get a whole new ring of cities where the rank starts from 1, but the rank within each ring goes up by increments of 2 instead of increments of 1. Building a FP (and SPHQ) in Communism always increases your corruption.
