I’ll throw in my two cents here.
I don’t have the newest A&A game so I don’t know about the pieces, variety and quality. I hear folks were dissappointed with the Italian pieces so I can understand bringing the Italians to market first. In my opinion, the next pieces should be the Brits. There are three reasons for this. First, the Brits are in every game except for Guadalcanal, so everyone that plays the non-worldwide games will want to buy this set, regardless of whether it is AAP, AAE or BOTB. Second, the original Brits share many duplicates with the Americans (same tank, same arty, same destroyer, same sub, same transport) so the new pieces will deliver the variety folks appreciate (eliminating the duplication with the Americans). Third, delivering the Brits will provide an opportunity for folks like myself to use the old Brit pieces for the Aussies in AAP until a FMG set of Aussies comes to market. This will deliver the biggest bang for the buck and will get more interest in the total project. There are many WWII games that don’t include Italian units, but very few that don’t include British forces.
After delivering British pieces, I’d like to see the Americans because I play AAR, AAP and AAG. Americans are in all the games so they will be in great demand. After the Americans, I imagine everyone wants to see the Germans. I would rather see the Japanese, but I can see that more probably want Germans. As a matter of fact, I expect many will want to see the Germans before anything else, but I have given my reasons for the other priorities. After the Germans we should see the Japanese, the Russians and then the Chinese.
Finally, I hope to see some FMG Aussies. Maybe Neutrals could be substituted from one of the other nations the FMG pieces replace until true neutrals are developed. I see developing neutrals as a difficult goal. How do you decide what sculpts to use? I would think French pieces would be ahead of neutrals. Anything that brings the whole 7+ nations to market quickest would be great.
