AtonementRPI has a pretty extensive crafting system- almost all of the equipment that the PCs use is PC crafted.

Armageddon has a large scale crafting system, although it can be kind of a process to figure out what all you can do and not do. The big part here is the merchant houses- in which characters vie for power and economic prestige across the game world. Probably the game in which the economic-political aspect is the most developed.
