This is the first paradox game that can legit kick my ass after I get the hang of it. Although it doesn't have all the bells and whistles of some other titles, understand that you trade that for a surprisingly competitive AI that can handle the same options that the player has. This is also the first Paradox game where I can lose a long game and have enjoyed the whole experience regardless.
The feel of the game is nifty too--there are no alliances: only plots, hostage exchanges, and varying hits to honor for DoW. It all feels very on the edge, and it is. Combing through characters for suitable wives is always interesting. The game usually forces you to face troublesome vassals. The game has a good sense of humor with some of the traits and their icons. A few things in the UI could be better but for the most part, this is a solid title that stands on its own as moving in a different direction than many Paradox games have done in the past. The game play is not as deep, but the AI and interesting diplomatic feel more than makes up for that. I approve.
If what I said jives with you, then yes it's worth your money. If not, no. Right now I am playing as a vassal. I started as a one province vassal to the clan lord, worked my way to daimyo, and now I am starting to think about how to take over the clan, or whether to start a civil war. My clan, headed by an AI but supported by me tactically, is kicking all kinds of ass, but every province my lord gets is one I may have to retake later. . . . It's cool!
