Patch 1.08
I certainly hope that 1.08 doesn't make these BB-induced wars HARDER to get out of. That would be ridiculous and lead to even more powermongering. In my game right now, Venice keeps declaring war on me every time I go to war with France. So do the Papal States and Tuscany. If they didn't make peace immediately, I'd be forced to occupy them (and trust me, it would be easy to do).
I have come to believe that something like the badboy value is necessary to keep this game from degenerating into a Civ-like conquest fest. But I also believe that the badboy value as implemented too closely approximates the 'contrived' challenge in Civ produced by an irrational computer hatred. If the BB could be based on geopolitical reality, that would be great. What I really think should happen is the BB should be tracked on a country by country basis (as has been mentioned, in one particularly brilliant post as well as other places) and therefore subsidizing a nation or paying money to someone would reduce their 'badboy' perception of you as well as increase your relations. That way, the rest of Europe might hate you, but you could always keep a few allies and maybe even a few powerful nations neutral.
I think this whole badboy problem is a poor solution to the problem it is supposed to be fixing. If we want to eliminate rampant annexations, then we should focus on the alliance diplomatic model and the AI's ability to run its country. My game is in 1703, on hard/aggressive, and France, Netherlands, England, Poland and Turkey are still using the halberd bearing army icon, meaning their land tech is below 14. That is ridiculous, though I'm not suggesting it is by any means commonplace. If we want it to be harder to conquer Europe, then Europe really needs to be competently run.
Addendum: I think that their tech might be low, now that I think about it, because they are at war so much with each other. Which could be BB related. Spain has been completely destroyed and prior to my editing, her BB value was at 25. France, England, and the Dutch fought them constantly in the 1500's and early 1600's so that could have retarded their economic progress. This value really is starting to have wide ranging consequences.
On the whole though, this is a serious, but not a critical issue to the game. The game is a wonderful experience and if you play it historically, it usually isn't so bad as Civ or Medieval Lords. Its harder to conquer people than other games because of attrition and war exhaustion. The diplomatic model is extremely interesting (easily the most entertaining part of the game is watching what alliances pop up and the computer's hatred of being alone in the world is very realistic, which leads to strange coalitions). They should adjust the badboy value, but I also think this issue should be put on the secondary list behind the crashes.
