Because once a new game is posted on AG and is reviewed by the admins, it won't be popular immediately, because it will take some time to gain popularity and attention. Also, different users have different interests when it comes to playing games.
I have to disagree a bit there invalid777... allthough what you stated is completely true, I suspect AG of giving some games a higher placement on the frontpage over other games. =/
In the past I've seen new games that didn't even make it to the frontpage of AG and therefor were missed out on. So not all games make the cut...
And to answer the thread's topic a bit... the popular games consist of mostly games that require to login a lot, like those multiplayer games and therefor have a high 'layed' rate rather quickly after being submitted. So the type of game has something to do with it as well...
The "Popular Games" list has nothing to do with popularity. It's a fixed list generated by the admins to promote games created by site admins or people that AG is sponsoring in some way. Games get popular from being on that list, not the other way around.
I think he entered his username in the topic bar instead of an actual topic like it should be, which is why it looks like he made two threads with a similar name (topic)...
