Eulora is an MMORPG with a real cash economy, published by the Ministry of Games. Mining is functional. You explore the environment (command /explore) and sometimes find goodies. If you find anything you obtain a (lockable) claim, which you can either develop directly (raw materials required) or trade away to another player. A total of 10 basic harvestables + 9 farming, 8 mining and 8 lumbering items (35 total) are available (along with dedicated exploration tools for each line). Crafting is functional. A total of 69 different recipes await your efforts (some of these are available from the merchants, and some require more advanced tools and equipment - which you can craft yourself!) The game has a dedicated irc channel for all your technical or gameplay needs : #eulora on Freenode.
