In the wiki we have a template for displaying coin and TP. For TP we display the USD value of the TP in parentheses.
About the real-world value of Turbine Points: When not on-sale (bonus TP), TP packages range from 400TP/$6.50 to 3100TP/$49.99 yielding a range for per-TP value from $.0163/TP to $.0161/TP. We have chosen to use $.0162/TP (based on 1820TP for $29.50). Of course, when Turbine holds a sale (adds bonus TP) the price per TP will be considerably less.
Question: How do y'all feel about that valuation? Should we be using the big package value instead? It would not make a BIG difference, but for large items like horses and such it would be noticeable.
