Ok, cheers mateYeah, neither Croatia or Serbia are actually part of the EU (in real life or on the game). However, within a year or 2 (Fairly sure it's near the end of the 1st season) Croatia join the EU, not sure when/if Serbia do!
That is wrong. I have never seen Serbia join EU in the game. In real life, they just recently became a considered member of the EU as they have normalized relations with Kosovo and apologized for the killings in Bosnia, but it is unknown if Serbia will join the EU and if so when. If it happens in the game it is a completely random event. It is correct that Croatia joins the EU in July though.Serbia need a bit longer to become member of EU, i think somewhere around june 2018.
