Has to be Brilliant, he has two fully completed estates, 1 uncompleted estate, highest smith guild level, high enchanter's guild and still has money left over.
He averages nearly 16 LG points per day. I can do that for a few days, maybe even a few weeks. But 3 years? It's mind-boggling how he manages to do that. That has to be some kind of gaming record.
While he has estates TAQQ has FSP in 6 factions. Looking at the FSP, I think he'd have all the castle buildings for probably at least 4 of those factions. Each one of those Faction castle buildings is a Lot of money.
