The Cost/Benefit change is much more clear!
One other thing I didn't realize was that the Heat track is shared by the group. We were playing that it was an individual track and I was wondering how anyone got very high on it. I think I might still adjust the amount of advancement on that for two players.
The stats were another interesting thing to read about in your log. Coming from D&D we interpreted them to be: Moxie ~ Str/Con, Smarts ~ Int/Wis, Wiggles ~ Dex, Friends ~ Cha, Pockets ~ as described in the log. Seeing how all of them (aside from Pockets) are more like FATE's approaches, I think we'll give it a shot next time and see how that works out.
