I tend to be in agreement with Stabbey. All in all, while a gamey GM mode might be fun, it wouldn't be a creation catered to the people that most want it. SCL made a gamey GM mode and many people were upset; they wanted the power to create imbalanced things. NSpace misread the market. Larian should avoid the same mistake.
That said, I hope we can mod in a mode like you're saying. That extensibility allows for a lot of ingenuity.
