I spent a great deal of my "last days of UO" doing nothing but crafting. My Blacksmith owned shops around Vesper and Moonglow and I could honestly spend my days just filling them up with stock.
I used to mine all my own ingots so I could offer competitive pricing.
Imagine - an MMORPG now where a resource actually changes each time it respawned (like the mines in UO where just because you had mined Shadow Ore a moment ago the respawn could be something totally different)
I spent so much time at the public forges doing repairs and making stuff for people. I built up my name so people trusted me with their Vanquishing weapons for repair.
....and all this on a 56k modem actually connecting at around 36k
