But I think the karma points shouldn't necessarily be connected to those more complex moral dilemma's. After all the dilemma's would be more like choosing from some options you wouldn't like. I think thats the idea, so giving you options you would like wouldn't make it that complex, and if there is an option you like, it isn't really a dilemma anymore.
So it's going to be tricky to implement those dilemma's and keep people happy with it. Because if you need to make a choice you really don't want to make it could ruin the game abit.
