Also for the whole period PLC stance was a very important factor in the Hab-Ottoman struggle. Lack of engaging representation of the whole elective shenanigans and the magnate/cossack factor is what I'm complaining about.
I think the appropriate treatment here is the events system. You don't need to mirror the actual government system the PLC had; you just need to abstract its effects into banes and boons and unique challenges that pop up under certain conditions. I'm sure Paradox will get that much right, even if it is a "tier 2" country by their rank of priorities. If Paradox is still thinking this stuff through, I have a couple suggestions for these events (positive and negative):
1. Grain Pays! The grain trade through the Hanseatic league is providing a boon to our whole economy! Ever richer nobles are reaping what they sow with great profits and even the peasants are feeling some small benefits.
- Maybe a small temp. redux to revolt risk
- Maybe some tax base gains or an income modifier that is temporary
2. Grain Doesn't Pay! The grain trade has begun to collapse! The wealthiest nobles, the magnates, are working their peasants to the bone for ever smaller increases in yields, but this only lowers the already plummeting price of grain.
- perhaps a redux in income modifier
- an increase in revolt risk that requires some deliberate counteraction by the player to overcome (i.e. taking some national ideas that promote equality)
3. Cossack Skirmishes
- relations penalty with a Muslim religion neighbor country (probably Turkey)
4. Cossacks Demand Privileges
- you can decide to increase the Cossack registry and face a noble revolt, or
- you can refuse the Cossacks and face their revolt in Ukraine
Ideas abound for such a rich history. I hope Paradox has some fun with it, so we can too.
