I just want to point out again that the issue concerning realism isn’t just about the number of infnatry, but where the infantry can be placed. This is the major reason why I designed the victory city infantry placement rules the way I did where the infantry placemnent maximums are per victory city and not per nation. It’s important for a nation to be able to palce some infantry close to the front lines to easily speed up the game and to realisitcally model how infantry are raised. I used the varying cost per infantry to create an incentive to place infantry closer to capitals.
You can say that the UK can use 50% of their IPCs on infatry, but if all the infantry are placed in London that’s not very realisitc IMHO. Many of the infantry divisions were rasied steadily at each of the commonwealths. This is one example why I think infantry placment limits per space (not just per nation) is important.
