So I'm suggesting a storehouse with limited capacity ( can be upgraded ) for resources buffs and so forth, for guild members to share. Depending on the rank, a guild member would have access to certain part of the storehouse.
This is a pretty common idea among online games, to share storage space with friendly community that the players are a part of.
however I'd add smth here. Guild Leader or Officer would be able to set a price of resource in guild house. Example: say hardwood planks for .01 coin, marble for .02 coin. So a guild member can get needed resources at a friendlier price but not for free. So I'm helping him but not discouraging or depriving of playing experience and building economy in order to obtain resources. Also by setting more prices, guild members could pay in hardwood planks for marble ofcs rate depends on guilds price setup.
anyway.
