Marchand, I agree with the bulk of your statements. Having played for almost 40 years now, I want simpler systems. Thirty years ago, I wrote a very crunchy system based on d12 dice pools. d12 is the ultimate die in my view - and you could give more subtle bonuses with a more fine number spread. It's all we played for 4-5 years. We loved it.
I don't know if it is a function of age or time to spend learning rules balance by family time, but I find that I don't have the patience for crunchy systems anymore. I have a great appreciation for all the effort that goes into crafting a workable system, considering possibilities, play testing, more tweaking, etc. As I build my rules light system, I am curious what people on this forum think. Sometimes these ideas spark a creativity thread that might otherwise not have gotten started.
