What features would you include in an AOE2 Randomizer?

For those who don't know, randomizers are games that have been modded to randomize various aspects, like A Link to The Past can have things like the items shuffled around into random spots, the enemies randomized, can have entrances/exits take you to random spots. Here are some examples of potential randomized modes for AOE2:

• Randomize resource types/costs. So for instance, trees might give 100 food each, animals give stone, stone piles give gold and gold piles/trade give wood.

• Shuffle civ bonuses: all the civ bonuses/team bonuses would be tossed into a pool, and from that pool every civ will randomly select 4 of the bonuses/+team bonus.

• Random diplo: at random periods of time who every is allied to random changes
