But one should keep in mind that they've also stated that the culture groups in vicky 2 are defined by different criteria than the ones in Eu3. The vicky 2 culture groups are all made with nationalistic unification in mind, unlike the ones in eu3 (probably for good reason as nationalism was still not the important force it would later become in the eu3 timeframe).
Some eu3 culture groups would require quite silly nations to have a union (yes I'm looking at you burman/tibetan group!)
