OK, my idea was in a Mastermind (BBC TV show) style.
96 contestants, pick there specialist subject (map, spoils etc., no map may be repeated). 96 contestants are split into 24 groups of 4. In Round 1 each 'show' has 8 maps. 4 specialist subjects, and 4 general knowledge.
Everybody will play all the games in the show. So DaveH, chooses World 2.1, foggy, etc. as his home settings. I pick Age Of Realms 3, etc. We have one game on Dave's settings, one round on mine; until everbody in our group has played on their home settings with the the three other contestants. We then play 4 maps of 'General Knowledge' Maps 5,6,7 will be random settings but map 8 will be Classic, Manual, Sequential, Escalating, Unlimited, Sunny.
Points will be awarded for positions 5 for 1st, 3 for 2nd, 2 for 3rd, 1 for 4th. If you finish LAST, you will get a PASS. (as in passing a question instead of answering). This is used as a tiebreaker in a tie of points. The winner of each group will advance with the 6 best runners-up. 30 contestants are split into 6 groups of 5. 6 winners advance to the final. The amount of general knowledge rounds increases by one each round, to keep track with the increase in specialist maps.
War doesn't determine who's right; it determines who's left.
