Swede will have to tell you whether Humbaba is the same as he was in BOTM 41. Maybe he has been resurrected as a different being
Somehow I just knew there would be some who have trouble with basic logic. The laurels will go to teams that win the game - assuming some do. The gold laurels will go to the team that achieves most of the ten objectives. If two teams achieve the same maximum number of objectives then the gold will go to the earliest in-game victory date of those teams. There is an unresolved question as to whether we distinguish two teams with the same number of conditions and the same victory date by comparing final scores, or whether we give two gold laurels.
It's not always necessary to do more in the next turn in order to achieve the second VC. Players quite often manage to reach two VCs in the same turn. In that case, the game only declares one of them, based on some internal priority processing, but both have been achieved. However, if you do this you will not need to do anything more after the "one more turn" sequence.
The turn after the victory ceremony might be used to finish any of the objectives - e.g. killing Humbaba or completing legendary cities or.....
I deliberately changed the wording of objective #1 to allow for the possibility that Humbaba gets killed by a rampant AI. It didn't seem fair to penalise a team who didn't get the chance to kill themselves.
