Losing a pop, tile improvements lost, tile being worked for free, research bonuses or setback, tiles with extra food are all very powerful events if they occur early. Others are only a big deal depending on what your victory condition is like free specialists or a free great artist

for culture games or bonus relations or lost relations in diplomacy games. The list goes on and on and I consider all of them as powerful or more so than popping a tech from a hut.
Consider 2 players starting out with the same builds and techs, one who works a cow and then has the tile wiped out so they have to pasture it again and then loses a pop for no reason versus a player who gets the cow worked for them so the worker can go mine a gold and then gets a research breakthrough and saves half of Meditation and then barely beats the AI to the religion.
I guess my favorite part of playing the XotMs is to compare games against others which is why most of my spoilers are pretty long winded, too long most of the time

, I just feel these random luck events make it very difficult to compare.
As Niklas says, in solo games they can certainly make the game less repetitive but in a competitive/comparison game I just don't understand what is gained by having them.
