It isn't, far from the best
i played a lot of Vicky 2, while you said you only played a single time, for a short ammount of time it seems.
i played lots of times, and as my 2 fav nations :
Brazil - 4+ until 1936
Germany - 6+ times until 1936
so yeah, there are more times i played until the end game, if i was you i would try playing more and seeing the flaws it has atm. you say terrible things of EUIII, yet seems a inexperienced player that only played it...blobbing over the infamy limit?
