For Japanese, M42-Dusters don't upgrade to flakpanzers and flakpanzers (type 87) do upgrade to mobile SAMs (for the rest of civs it's opposite)
Belofon, thank you very much for reporting this error.
The type 87 was not added to the upgrade chain. This is fixed now for the next version of RARR. The upgrade of cannon AA tanks to SAM vehicles was generally stopped. So the SAM vehicles have a better AA value, the cannon AA tanks have a better defense value.
Some unit entries (at least for siege artillery and Asian warriors) are empty:
For some of the civilopedia entries of those units in the present version of RARR, the CCM civilopedia entries should be seen if the CCM 2.50 expansion was installed properly. I attache a screenshot of the current RARR civilopedia entry of that Asian warrior. But those entries must still be adjusted in the unit value part of those entries. The entry of the siege artillery until now is missing completely.
No Cold War tanks for Persians:
Belofon, again thank you very much for reporting this error.
The Persians now have the M48 as their cold war tech tank.
About your interesting suggestions:
What about changing of upgrade path for great galleases from frigates to SOLs? Frigates and SOLs become available at the same tech, and IMHO the GGs, as the most powerfull ships of their era, should upgrade to more powerfull SOLs while cheaper and weaker galleases would still upgrade to frigates with similar attitude.
I have a problem with the categorization of those ancient great galleasses, as I consider them as a kind of a 'phantasy ship' and therefore I have a tendency to cut out these ships from the mod - but due to the respect for the old creators of DyP and RAR, this ship is still in the RARR mod. The galleass is more a coastal ship, while the SOL is a heavy oceangoing ship. I think, with the current upgrade settings, the combat values of the ancient great galleass are improved enough. It is not intended, that the player should build masses of those "phantasy" great galleases only to upgrade them later to SOLs. Additionaly this would unbalance the construction of smaller vessels compared to heavy vessels even more in this mod.
What's the point of ever using cannon galleases (btw, another unit with empty entry)? Their stats are worse than stats of much older GGs (while their cost is the same) and contemporary carracks (which aren't that expansive in comparison with cannon galleases and also appear in main tech tree); at the same time, they aren't that stronger than normal galleases due to their much higher cost and late appearance. May be they should be a bit cheaper or they should have better stats (like 5 or even 6 attack and/or 3 defence)?
About the civilopedia entry of the cannon galleass, the same has to be said as for the other civilopedia entries. With a proper installation at present you have the CCM civilopedia entries for this unit in RARR. The stats of the "cannon galleass" are better than the stats of the old era1 galleass (A4,D2, Bomb8 compared to A3,D2,Bomb6).
Not mentioned in the current civilopedia entry of the "cannon galleass" is, that this unit also has one additional HP. In the next version of RARR, the upgrade of this unit will be changed to a corvette. At present the purpose of the"cannon galleass" is to be a unit for upgrading the era 1 galleass. In the next version of CCM it is intended, that this unit will be a part of a line of units that are faster in coastal waters compared to normal units. This needs a lot of work in the settings and civilopedia entries of many units (and the coastal terrain) as the movement cost of coastal terrain must be risen to two and the "coastal ships" must receive a movement bonus in that terrain. That´s why the CCM civilopedia entries for those ships are not reworked yet (as it is for the galleass).
Compared to carracks the "cannon galleasses" are cheaper, but they cannot cross ocean terrain and don´t have the enslave option. In the next version of RARR they will move much faster in coastal terrain compared to carracks. May be I could add the enslave option to the "cannon galleasses", too.
Btw, hasn't this system already been added to game in form of the great monastery from theocracy and holy men which it spawns?
This is only a very slim part of the system of holy men in CCM 2.50, that was cautiously implanted into RARR. The most crucial part is, that these units can convert other units to monks and these monks can be 'added to contribute to the cultural benefit of a city' to expand the city borders to the next size. As many CCM succession games at CFC show, this 'cultural bombing' is one of the most liked and best concepts of CCM, as the AI is using this option very well, too. Additionally this concept helps a lot against units from other civs, which are stepping across your territory.
The next level of this system are lawyers and great artists. You can read more about these concepts in the CCM thread.
Edit: After having a look into the RARR mod I see, that I have indeed implanted more of that concept in the current version of RARR. When this concept is implanted completely, it is no longer government specific but generally available in the game.
