You must have a very, very different concept of what "respectable weekly income" is!
Well, my numbers might be off since it was over 4 years ago but it worked out to around 50 gold each which, at that time on the EC was the average character income. And who said building a recruitment center was even on the list of things that needed to be accomplished?
You also have a very very strange concept of fun.
Run court all the time and wave your big knight dick.
Well, yeah. It wasn't just clicking a button once a day and writing one message saying "I'm important look at my knights!". It was the interaction of 7 people roleplaying at once. I won't go into detail since this is off-topic enough as is, but to put it bluntly the fun came from the interactions and dynamics of the mini-duchy I built rather than watching my 50 man unit silently beat the crap out of some other guy's 50 man unit every 3 days.
The reason why places like Oritolon march across entire continents is because they don't even have enough nobles to hold what they have, let alone pick an expansionary war with a neighbour. Back in the day folks, we used to be able to go to war with our neighbours.
This ain't TravelMaster.
I think this is part of the mindset that creates this issue with estates. I have one real question and several rhetoricals:
Why must wars simply be fought for conquest? Why is it that the only way to wage war is to forcibly remove the other realm's influence from a region then put your own nobles in their place? Why can't you use gunboat diplomacy to force the lord and his knights to defect? Why can't you go on a raid, steal some gold, and go home? If a realm insults you/your king/your mother, why can't you simply crush their standing army and force them to appologize without conquering half of their territory?
Hell, look at Dwilight. People whine and complain about how the continent is so big and that they are lucky to have 1 knight per region
and yet realms are still expanding into the unclaimed territory. Its not purely the fault of the estate system. Everyone wants to conquer new regions and spread out the few nobles in the realm because it gives them a chance to move up in the pyramid scheme that is feudalism. I won't say if this is good or bad, but you can't only blame the system when the choices people make are just as responsible.
