Ruby

Rubies in MaddTech are meant as a currency. 1 ruby = 8  mini rubies. Rubies come from ruby ores.

The recommended economy model on MaddTech servers is that all players start with a predefined amount of money, and progressively find more rubies, without telling anyone that they had found them, which helps prevent inflation.

Using this system, as cities on MaddTech servers develop, prices will go up at roughly the same rate as resources become available, enabling the economy to work.
