I played the demo, but I still couldn't tell if it is worth 40 bucks or not. I usually enjoy most Paradox games but this one "seems" different. My biggest problem with the game was the learning curve, it seems like the game tries to be as complicated as possible.
(Also any tips for how to play would help :P )

Have you played the first one?
When the first one was released it was easily the most complicated game of the series.
I am not surprised to hear that Victoria II continues the tradition, but I read plenty that the sequel was going to be more streamlined than the first one.
Suggestions? Hmm, get a small country to run and focus on one thing, economy.

Seems to be getting very favourable reactions over at Gamersgate and the Paradox forum. I'll definitely be getting it end of this month.

Wait a year for the expansion to be released.
The game is playable and a lot better than HoI 3 but it is damn terrible when compared to the original. The pops system is completely retarded where you have Swedes converting to be Afro-American pops...Yes! The whole upper house system is stupid as hell.
All of this because Johan is an idiot.
I liked Victoria 1: Revolutions by a long mile and by that I mean I loved that game like a son.
PS, Carlist Spain is the best Spain next to Falangist Spain.

Almost as stupid as having africans or arabs going to Sweden and getting the Swedish citizenship? I don't know, it sounds realistic to me, at least up to a point.
Mind you, I don't have the game yet, I am just going by what you said.
Who is Johan and why is he an idiot?

Victoria 2 is being talked about in most strategy forums I frequent as actually pretty good on release...something of a miracle after the disaster that was Hearts of Iron 3. Some find it too complex, others say it's too automated.
There is a demo available, so I'd suggest giving that a try, Razzoul. Lets you play out the first 15 years of the game, so you'll get some idea of how it's set up.

This is set during the era of national awakenings. Sure, you can have people of similar cultures assimilate to the dominant culture. But, cultural outsiders shouldn't be assimilated. The rate of assimilation is silly as well where by half way through the game or so you'll almost have an 100% cultural homogeneous country.
Johan is a Paradox developer where most of the problems with Victoria 2 is with his ideas.
You see, fascists and communists can ally with each other because they hate political reforms and want to give social reforms.

I like Johan, I played the Soviet Union in HOI3 and I pulled Japan into a communist state, always wanted that to happen. I'm not being sarcastic, I'm serious ;)

I tried the demo again, but once again I failed horribly.
It seems like I run bankrupt in only a few minutes.
This game is way to complicated for me!

I'm going to wait for a sale. I just sank my teeth into Europa Universalis III and Heart of Iron III last month and can't stop.

I don't know if you've played the other Paradox's strategy titles but U need to take time to learn how to play Paradox's games. Afterwhich you can't stop playing anymore. Heart of Iron series tutorials are useless. I had to read the manual, play Hearts of Iron 2 and then play a few starting Hearts of Iron 3 games before I really embarked on my real campaign. You could say it took me a month to really learn how to play Hearts of Iron 3.

Apparently the Vicky 2 tutorials are ACTUALLY GOOD. I may check the demo out just to see that. :)
Razzoul : Start with those. READ THE DAMN MANUAL. Pick a country and take your time. Play around with it and see how it works. Also, there's apparently a 90 page strategy guide that is free for any buyer to download available from the Paradox Victoria 2 forums. Go get that and give it a read.

As the game stands it has some crippling bugs which will be fixed by the upcoming 1.2 patch (however, shipping with game-breaking bugs is a Paradox tradition).
For example, there is a problem with the way rebellions are handled, so by the 1860s you end up playing whack-a-mole with hordes of Jacobin and Anarcho-Liberal rebels popping up in your country, and there's little you can do to placate them.
The late-game economy is also a bit bugged and your capitalists tend to make silly factory building decisions.
All that said, it is already a good game, and with patching it will be excellent.

Victoria 2? That's so outdated :p - Victoria 4.2 is the one to go with!
