I played out the game, as far as I could over and over again without the walkthrough, at least till I went to war with the Incubus Emperor and learned from previous mistakes, so I would like to see what would happen if I could invest in everything possible (that actually generates PRoN)
Thats the only issue I kept running into through out the game, I am sure I did more then enough with the ProN I had available going through standard game play. If you watch the attention of Magail and Simon when there's a real good opportunity gain both ProN and supplies then you should seriously try to invest.
Usually Banks, Equipment (Armor, Weapons), Ore, magic crystals, and a few places who can make the rare material into something useful to Simon's team and the rest of the surrounding countries!
I should have never really said anything about using an editor to cheat a little, but I did notice some silly dialog from the dev who seems disappointed with players going this route, which I am fine with.
Did anyone notice two cloak persons in the Stineford Market, directly to your left from the Armor Merchant? I tried to find a way to get to them, (hidden doors) on the Market side, and the other side (Building with an Orange roof)! Short of looking through the entire walkthrough (something I do not like really doing) is there anyway to get to them? Or are they a problem further down the road.
