Playing as a small nation is indeed dull, depending on how you do it. There ARE ways to create CBs, and give you non-stability-killing wars, but they're more limited for smaller nations. Here's a few of them:
- Claim someone's throne. You need a royal marriage with them first, they need to have weakened legitimacy, and then you claim their throne. If someone ELSE claims the throne, you end up in a succession war. If not, you basically get to rule their country (although I don't think you annex them, so when your ruler dies, they may get a new ruler and break off from you again). Still, that CAN land you in a war.
- Form alliances and hope that an ally calls you into a war. Doesn't always happen, but it can. That gives you the "Alliance" CB.
- Go on crusade. Wait for the Pope to declare a holy war on...someone (probably one of the north-african states), and go grab some land. It won't be great land, but it's worth a shot.
- Sometimes you'll get a mission that gives you "Conquer [neighbor]". These missions ROCK. You get a free core on the province once you win, and it's not as expensive to win as when you go to war without a CB.
- Sometimes someone will get a "Dishonorable Scum" CB against them. Frequently, this is Burgundy in the early game. Once they get this, ANYONE can declare against them. You can also try allying with one of the majors like France or England (or Burgundy) to get called into wars with one of the others.
- Excommunications against someone also give you a "free" CB against them until the excommunication is lifted.
- Sometimes if you develop enough trade and compete away enough other traders, you'll get the embargo CB. Not a great CB, doesn't let you gobble land, but you can at least build prestige.
- There may be Holy Roman Empire politics you can engage in to try to get yourself to become the Emperor, which will likely see you involved in plenty of wars.
That said, playing as one of the smaller minors is VERY hard and/or boring. You don't have a big military, so you have to rely on trade and teching to get ahead. You have to play the diplomatic game pretty carefully, in order to gradually expand. You're often land-locked, so forget about colonization. It's NOT easy.
Best nations to start with, in my opinion, are:
- Portugal
- Castille
- France
- England
- Burgundy
Some of the other central powers (Bavaria, Bohemia, maybe one of the German states like Brandenburg or the Hansa) can be interesting. There's also Muscovy and Novgorod, and Sweden. The first two typically end up fighting non-stop with the Horde, but Sweden also gets a nice little self-contained game where you can build a little baltic empire.
Still, a one-or-two-province German minor is a very esoteric game, and one that's pretty hard to play or get into, in my opinion. Your missions are probably boring too, like, "Establish a center of trade!" Great. Build up 500 gold, plop the thing down, and...uh...gain 10 prestige. >yawn<
Like I said, if the interface isn't for you -- too hands off, too slow between game feedback events, etc. -- no worries. You shouldn't force yourself to play something where the actual ACT of just PLAYING the game bores you (forgetting about the outcomes, I mean). There are games where I have fun losing, and games where I'm bored to tears winning. The PLAYING of the game has got to appeal, after all.
But I'd say you've only experienced a fraction of what actually playing the game is when it comes to EU3 if you played as the Palantinate. You've got a sense of the interface, certainly, so if that's a huge turn-off, you may be making the right call by moving on. But in terms of the game options, playing initial games as The Palatinate would be like playing a game of Civ5 as one of the city-states. "I know! I'll play the next game as Hanoi!"
