Quality vs. Quantity (Score 1)

I'd like to take a moment to remind everyone that numbers are not always best. You can play the most crowded, popular MMO, but it you may find your quality of play degrading as more people arrive. It all comes down to game design and the quality of the environment you play in when determining game quality. I've had some of my best gaming fun on small MUDs with a userbase of only 200-500 or so. That's largely because the environment was well crafted, the players were of good quality, and so were the admins. I've also had a good bit of fun on underpopulated servers on World of Warcraft, a notoriously crowded MMO.

So while I'm definitely not answering the question posed by this thread, please consider the above when comparing your MMO's to one another.
