15600 games?
I don't know if this is a good idea.
I preffer quality than quantity.
Users will play games on your site and if most of them are boring, why they should come back?
my 2 cents
I agree here with Gluss. Its going to be impossible to find a good game to play unless you know the name. Most users will only browse a page or two before the split because the next site they go to they'll be able to find the game. Id advise to show 300 or 400 HIGH QUALITY games. Gotta make it easy to find games! Too many sites out there are watered down with crappy mochi games. Goodluck!
