Well, I couldn't wait for the English translation to come out, so I downloaded the Russian-language full campaign. My first impression is that it is absolutely awesome! The music, the campaign map, the UI, the new units, the sense of atmosphere - it all combines to be extremely enjoyable indeed, and I can really appreciate all the effort that must have gone into it. I do have a few points of helpful criticism:
1. The kill rate seems quite high. I sent my Moldavian spearmen into battle (and admittedly they are quite rubbish troops anyway) and they were butchered and fleeing for their lives within moments of approaching the enemy. I would prefer longer battles with higher morale.
2. A limited area of recruitment system would be quite nice. I played as Moldavia, and they have quite a limited selection of troops who really aren't very good. It would be nice, once I have conquered new parts of the map, to get access to other factions' soldiers as well to add variety.
3. The smoke on the battlefield sends my frame rate plummeting and makes the battles go a lot more slowly. Is there any way of reducing the amount of smoke produced by the guns?
4. I've noticed that the movement distances for armies on the campaign map is extremely large to make up for the fact that there are only 2 turns in a year. Perhaps you could implement a 4 turns per year script so that the movement distances could be reduced? At the moment it is too easy to outmanoeuvre the AI on a strategic level.
5. I noticed that you simplified the building tree quite a lot. On the whole I like this, although I enjoyed the old differentiation between different types of roads.
6. I think that perhaps there are too many settlements on the campaign map. It makes it extremely difficult to manage things (especially for Moscow and the Ottomans who start off with enormous empires) and means that most of the battles are sieges, not field encounters. It's not a big deal, but I would prefer it if there weren't quite so many cities.
That is all that I can think of right now. I must say again, this is an extremely enjoyable mod, and I can't wait for the English version. I've managed to muddle my way through so far (I can read Greek and so am just about able to make out what the Cyrillic letters say), but it is very difficult. With a few extra tweaks I feel that this could be a truly sublime mod.
