I copied TMIT's idea a while back, disabling every event. Since it can take a while to change it, here's a rar of the XML I use.
For future reference, I suggest using the find and replace command in word or openoffice, which with a few wildcard characters makes switching all the values to 0 take about 30 seconds...1 minute if you count starting the program up and messing around on the internet for a few seconds before going back to it.
Find and replace is a powerful tool for a lot of XML based editing, actually

.
In the game I saw posted, had the player hedged against the event by building units, he would have turned a sure loss at turn 30 into something better than that, possibly a win.
It's fine on weak levels where you can just use the warriors to kill a hapless sucker AI shortly thereafter.
But on high levels this statement is sheer ignorance. You hedge against this garbage, you lose. You lose several city sites, handing them to a now-larger AI that can easily afford them. You lose spawn busting regular barbs from appearing, further locking you into your city. You lose out on valuable worker turns, stifling your empire wide development by literally double digit turns at least.
Try that at immortal or deity. Build up 4 warriors to start while working unimproved tiles JUST IN CASE a rare event might hit you. See what happens.
If you are a deity player dropping to immortal, you can probably recover. If you're not, good game. Be sure to lose the next one by doing low-odds hedging too. Maybe that's fun to some people, somehow.
