Sounds good. And I trust Tinto.
It makes sense to focus on the most played nations, although I would have expected this for the last DLC and I hope this is not it. No matter how much we might want EU5, there are still some sad regions in EU4 that desperately need content, like South America, and its colonial nations.
I share the sentiment that getting DLC for nations that were already reworked in previous DLCs leaves a bitter taste. Although it's minimized when the content of those DLC get expanded for free, like in the case of Golden Century's Holy orders.
Still, a questionable use of DLCs overall.
To me, mission trees are not what makes EU fun. Content should preferably be about new mechanics; things you can do in the game, and flavor for that sweet immersion. Missions go against the free sandbox feeling of alternate history that draws me to this game, but at least missions are optional and I guess some people like them. Unlocking special units through missions is fine.
I want EU4 to be the best it can be, so I'll keep supporting it. I also wish to keep loving the brand in the long term, but a good DLC policy is essential for that.
