| 35 | = Rarity = |
| 36 | Not all items are created equal, dirt is literally ''dirt cheap'' and diamonds or rhenium ingots are extremely expensive. This implies two things for each item based on its rarity: |
| 37 | 1. A starting / initial cost |
| 38 | 1. The rate of increase / decrease for each item |
| 39 | |
| 40 | == Issues to Consider == |
| 41 | 1. Is the rate of increase / decrease related to the initial cost? or is there any reason they could be independent? |
| 42 | 1. Does the rate of increase / decrease change? or is it fixed based upon rarity? |
| 43 | 1. How are initial values for each item going to be calculated? |
