In for next version, based on discussion mainly on 1.008/9 thread:
* The deaths of bandit units and buildings now contribute to your score, where previously they did not.
** This is done for a number of reasons, mainly to avoid confusion and an arbitrary-seeming rule. This also avoids encouraging a particularly defensive playing style above all others.
** Older savegames have been updated to include score for prior yellow deaths at the current going rate of whatever your current age is. So in other words, you get off easy with extra points in the ages of monsters and gods compared to the age of man. This is going to make the bandit deaths look way more valuable than the red and blue ones in that savegame, but that's just due to the upgrade and is not a bug.
* The score gates have been increased by 15% across all of the ages, to account for the roughly 15% extra score (on average, but it will vary heavily) you are likely to get from the fact that bandit units and buildings are now granting you points on their deaths.
** Existing savegames have had their scored points increased by 15%, to prevent situations where you automatically lose when opening an old savegame in the new version, etc.
