Certainly doable, I think. I'll just have to look up the siege condition and put in a decent likelihood of happening, with a modifier that makes Mongol sieges in Russia much more devastating (something like 10X likelier). Though the problem there would be that Mongols have too much money and thus just repair it immediately afterwards (I probably should check what their tech levels and progress speed are, should probably severely limit any but military tech from progressing so they won't really rebuild).
While at it, I probably should get around to making that early negative modifier for BE (along with knocking it down to a titular title) along with more aggressive Turks. And make it so HRE has a very hard time to establish a centralized authority, much less getting rid of Elective (actually I should probably split the unwillingness for stronger Imperial authority through laws between Elective giving a penalty to approval of tighter Laws along with just being HRE).
EDIT: So, until someone helps me come up with ideas for events/decisions/whatnot for Finnish pagans/tests out the unification Invasion CB, I'm going to work on the following:
- Siege-caused building destruction events for all sieges.
- A *lot* more of those events for goddamn Mongorians in Russia.
- Mongorian has no time for love, only war (tech modifiers).
- BE taking it up the ass from the Turk.
- Titular BE instead of de jure.
- HRE shenanigans.
I'm not going to work on plagues and such to as large of an extent. I quite like the arcade-y touch of the vanilla gameplay, so I'm trying to conserve it as much as possible while improving historical aspects.
I should probably do something about France too if I'm going to do things to HRE and BE. Or should I? How's everyone else's experiences with France?
