The rationale i see for using Python for item transformation is that it's not a required feature to play the game. Same for bank actually - you can play and do many things without the bank system. Same for gps, and everything in Python scripts. It makes the game more fun, but the core of the game does not depend on it. As for transformation "formulaes", they still are hardcoded in the archetypes, so Python doesn't enter the equation so far. Or I could use Python to let players/DMs alter ingame changes, by storing formuleas in a Python object saved on disk. Nicolas
