I suppose one thing that is kind of unfair/misleading is the fact that people have their games on different speeds. I don't mean timewarping, but having your game on Fast will give you much higher results than someone on Normal or Slow.

The other issue is that the Leaderboard doesn't really give new players a chance to get on it.

Looking at that Leaderboard - the majority of the results on it looks suspicious. I have three villages of the same age, all on fast, the only difference being Easy/Normal/Hard. They are all on pretty much the exact number of Twins, Triplets, Events, and so on. Yet on the Leaderboard, the events and hours played do not appear to correlate.

I am also curious about the 101 village population. That would require several sets of triplets being auto-born (ie generated in the log files, and appearing when you start the game) at once. I suppose it could happen, but it seems a very rare chance.

EDIT: I have attached some screenshots of my stats for reference. I have never timesurfed with these villages.

What you will notice is that the villagers die much younger on Hard/Difficult level. Therefore there is more "room" to have more babies, and so more have been born in this village than the other two.
