This isn't a request, or a "ahh, help me moment" but an idea someone could do, to try and get the community back as it was, to inspire young/old developers to open and develop games. Anyway, this is the idea;
You mine for ore, and with that ore, you can upgrade your items. A simple concept, and potentially enjoyed by many players.
upgrade_items, with the following columns;
id int(4) PRIMARY KEY
ID For indexing
ore_needed store an array of values, separated by a comma, explode the comma, to see what they need. Stores itemID's from the items table
item_from this is the item that you are upgrading, a numerical value.
item_to once you have all the "ore_needed", this is the item you get once upgraded.
Anyone who makes this has full distributor rights.
