After "talking" with Safferli, I am removing the poll/question. Deus Eversor is correct, this would turn the AAR into an interactive one, something that I clearly don't want.
1-So, after reading the comments, I have decided democratically, and only with voting (as you could expect it as being the Chancellor) to not release the western RKs. One of the reasons is that the Western RKs "ruin" the map and prevent the deployment of province improvements later in-game. And no, that is not because they are useless! I had actually started to play 2 weeks with them released before asking the question (I will revert to the February 1st, 1941 save) and they are actually very good. For a loss of 7 German IC, they have together an output of 25 IC (even after the Independence struggle event) and bring something like 400 mp. Even if they have a -25% research rate, it is more than compensated by the +50% that they would get from German blue prints. I wanted to release them mainly to squeeze more money from them, and didn't expect that many collateral bonuses.
2-I have not decided for RK Norway, but I won't release Scandinavia as it will be impossible. Before a release, I would have to put a claim where the nuclear reactor will be deployed by event, to be sure that this reactor won't be controlled by RK Norway. And if Germany keeps this province, then Scandinavia can't be released.
3-Bosnia? I will see. What is weird is that there is no or almost no dissent there.
4-Eastern RK? I will very probably release them when they will be available.
There will be no update before next week. Have a nice week-end!
