This is an update on my first game: Castille -> Spain. Again, no mods, no cheats (in fact, looking for achievements), easy difficulty and the rest is default config.
I'm leading PU's with Sweden, Muscowy, Lithuania, Ukraine, Moldavia and Wallachia, so I'll pretty much get rid of the inheritance system, since the rest should be annexed in a future when I form the HRE, so it will be time to switch to a republic, I guess. But not for now, as I'm bordering a lot of hordes (mmm, land for free, "me wantee") and people say that you can't inherit while at war with them... I'll give it a try now that my next objective is to lower my infamy.
Europe, Africa and Asia:
During the last 40 years, I focused on Holy Wars and waiting for the opportunities to force PU's claiming throne mainly or using spies in few situations with the last big independent european nations. I started "colonizing" the India for the achievement (I should have waited, since I think I have enough time to do a WC) and, just after I met the hordes in person, I offered them no chance to retreat, consuming any province bordering the empire and increasing the land size considerably.
World map with PU's & vassals:
Current objectives: Set up a land connection with north Africa, finish off all of the hordes in case I couldn't inherit because of bordering them and, in summary, Holy War FTW below the infamy limit! Forming the HRE can wait (personally, I don't like the tag nor the color so I'll let it be as a low priority...).
