Zerg - And what that means?

[jepaul]

So I read, and agree with the posts, about zerg outfits this, zerg outfits that.

But what is a zerg? I understand the definition so no need to explain.

But in PS what is a zerg?

Is it 30 people? Is it 50? Is it 100?

If the goal of the game is to take territory and win wouldn't a "zerg", or superior numbers, be the best way to do that?

I ask because there seems to be such animosity towards "zergs". So I ask, what is a zerg, and what exactly is wrong with it?

If a group of 200 have fun playing together and they are able to manage those numbers are the groups that complain about them simply complaining because they can't compete against a "zerg"?

So the questions is. How many people in PS2 constitute a zerg?
