You better get as much out of EUIV as you can. Though EUIV is much better now than it was at release, it pales in comparison to Vicky 2. It's like switching from classic CRT TV to Widescreen HD TV. You don't know what you're missing until you try it. Then, it's hard to find any other game that comes close(I've only found one that is potentially as gratifying).
The same as many here, I've played strategy games for almost 2 decades now, and Vicky 2 is my gold standard for what a strategy game should be...not so focused on combat/conquering; no single formula for winning; every game has a unique set of circumstances that will change your overall strategy for reaching your goals. Turning Siam into a Great Power and keeping it in the Great 8 is, in my opinion, a greater and more fulfilling achievement than being number 1 at the game's end with France.
TL;DR: Regardless, You're wasting your time with EUIV. This forum is chock full of guides for Vicky 2 that will get you off the ground. go search for
