For the most part, what ever equipment your RPG system uses, should be good. The only difference, as a GM, you should worry about is the money system. On Maratpa the money system is as follows:
2 Half Pennies = 1 Copper Penny
5 Copper Pennies = 1 Silver Eagle
5 Silver Eagles = 1 Gold Ducats
5 Gold Ducats = 1 Steel Knights
10 Steel Knights = 1 Platinum Dragon
To translate into your money system, Gold Ducats would equal Gold coins in any other game system.
