I'll have to give it a read, at 58 pages Into the Woods isn't exactly tiny. Sounds about right though, from your description. Meanwhile, to answer your question, I mean a system that doesn't require decisions to be taken for enemies during combat, removing the need for either a game master or AI. Fewer dice rolls are a bonus, though that's much less important when a computer does all the math for you. So I came up with this concept where enemies have an overall combat score (it's not like you should be able to see their exact stats anyway). You roll the dice; if you beat their combat score, you deal damage. If you fall short, you take damage instead. Variety would come from which of your stats you roll against and various (dis)advantages providing trade-offs.
Of course, as always the devil is in the details, hence why I started this conversation. Thanks for the help!
