Quite frankly, I am not liking that. As far as I know, leaderhead infos haven't even been made for many of those civilizations, and that's not the full extent of the problem, either. I see no reason why so many member states have been split out of the European Union, when it's become such an important player in world affairs. These states will be more powerful together (a potential rival to the USA, as in real life) than they will be individually, and this is especially so with Civ4's bias towards large empires when determining strength. Furthermore, the EU as it exists in that list is going to be fragmented from itself--not a good thing. I say return the arrangement it had in the screenshots released in the map thread; that is, controlling everything in Western Europe but Switzerland, Scandinavia, and the UK.
Then, there's other states that need more representation because they can't be lumped so easily with the ones next to them. Mongolia is a democracy with a primarily Budhist population, bordering China, an undemocratic country with controversial relations to Budhism--that's important and needs to be addressed. Same with the more liberal, hedonistic United Arab Emirates being next to theocratic Saudi Arabia--somehow you need to address that. We should end up under 50 if we make all those changes, so I think we ought to do so.
