Yeh can't never. If you like try to get LV99 on every game or something like that.

Here's another:
www.freewaregames.net

Here is a website filled with user created games.

yoyogames.com

It has many games created with the software Gamemaker. Some are not so great, but there are plenty of very good games. This is also the main website for the gamemaker software, so you can get into some game development here.

I suggest trying out Lab 9 first. One of the best games on the site.
