While I'm looking at Fuzion stuff, I found this fascinating article about how it came to be...
Fuzion RPG design
It's interesting to see how the designers took two sets of very different rules, seeing that one set performed a specific range of function well while the other performed well in a different area...then tried to create a generic toolset to cover all styles of gaming.
Reasonably successfully given the number of games that adopted their rules (both professional and amateur).
That's all for now.
