I am not to good with prices. especially with an untested economy... so ill leave that to some1 like bow or some other mod. ill say yes or no and put a reason next to the nos and some of the yes's.
diamonds (yes): since they are rare, and xp can come quick, we should sell these, but somewhat high
iron (yes)
coal (yes)
netherwart (yes)
glowstone (yes)
potions? if possible (no) : it would be to much to set up a potion pricing system let alone a section in the shop.
bread (yes)
cake (no) :
mossy stonebrick (yes/no)
cracked stonebrick (yes/no): im torn between this and mossy. i personally would like to see these as rare mats. Cardinals keep (my first dungeon) also gives i think 50 of each at the end.
stone (yes):
infinite stone brick (no) : I see where u are coming from liquid when u want this, but it will cause more problems than its worth. first, stone would be going for 1xp a stack eventually. second, if some1 feals like trolling and has enough xp they can go do some damage. yes we can roll it back, but it might turn into a big head ache that we can avoid.
lava (no): this can possibly cause some problems. yes people can easily go down to a lava pool and get it with a bucket, but id rather them do that than easily pick some up at their local liquid shop.
obsidian (yes) :
netherrack (yes):
netherbrick (no) : since its a recipe and we will have a nether dungeon that will give netherrack (plus the stuff in the shop) i think we should keep it a "rare" item.
netherfence (yes): i say yes to this because idk if we have a recipe for it. if we do, then i say no, we shouldnt sell it.
sorry for the book, but id rather we talk it over now than after a problem occurs.
