I actually found some hideously overpriced armor and weapons at Maranuth. To wit, one spear priced at 117,000 denarii and the body of imperial lamellar for 90,000+ denarii (no gloves or boots though). Town only had 58,000 denarii so I have no idea where they got the weapons from, but dey was dere, I swears it.
The devs seriously need to fix the money part of the game. One spear is worth more than the treasury of the entire town, seriously? Not a super-weapon of mass destruction, just a kind-of-okay spear that happens to cost 20 times more than it should.
