Ground Rules
 

Score in Might & Magic IX is measured as (the party's experience / 1000) / Time, where time is the number of days completed (NB hirelings do not gain experience).
With respect to score, a new day starts at 6:00 am.
Experience is gained by killing as well as by completing quests. Since the outcome can be influenced by other factors than merely good gameplay, a few groundrules are necessary to make scores compatible. The following "cheats" are out.

[1] Respawning (eg Training Hall, skeleton machines)
[2] The learning skill (a bug, it should affect experience but not score. On top of that, the Grandmaster Learning effect is tenfold by yet another bug)
[3] Dying on the Isle of Ashes without doing the initial quests

If these ground rules are not followed, scores will be uncomparable.

Let's see, how high scores can become if the ground rules are followed.
The following table shows how much fame is involved with the quests in Might & Magic IX.

Total of all awards 873025

Additional fame comes from killing foes, including any Arena fights, and even from killing friends. Note that while awards give a set amount of fame to each character, experience from a kill is divided among all conscious party members.

There is sufficient prey in the game to reach level 58 before entering the final dungeon. The fastest time, estimated to be 33 days, may not offer enough slack to attain a maximum score. For that, one extra day of killing seems required.
