Random Event Modding - Must Good always give penalties?
So I got fed up with the way the random events always seem to penalize Good choices while rewarding Evil choices and set about to modify the random events to be more balanced. Ideally, I would have made each choice raise one stat while lowering another, with Neutral hovering between the two, but it does not seem this is possible. Thus I decided to simply make it so that all three options give a bonus (or, in the case of certain events, a penalty) and it is simply a matter of choosing which bonus one prefers.
However, it seems I have been foiled even at this. While playing with these modded events, I chose an option that claimed to give a "+-25% Research bonus", which turned out to be a -25% Research penalty. I checked the file I had modded and I'm pretty sure that there was a positive value listed, not a negative value. I'm not totally sure, though, and haven't done very extensive testing of this mod yet.
So, does the game force Good choices to be negative? Has anyone else attempted to do this sort of a mod?
