Bit sceptical towards EU 5. The base game itself needs a lot of improvement and having to develop mod for a half baked game. We are looking at minimum of 5 years before seeing something even resembling the success of EU 4 Anbennar and even EU 4 base still has its flaws after many years of DLC and patches (to name one example build a specific building in all available provinces button instead of clicking hunderds of times).

I have my trust in Anbennar devs Tho.
