I normally don't give a rip about flash game sites (in fact I go into the code and play the game full screen so as to avoid them). But apart from to many ads this one was nice.
It has several categories etc. But what I like is that you can rate and comment on games without creating an account.
You can also earn points by scoring high on games (I can't find anything to use the points for yet, though). But the site shows good potential. I can't find any way to learn about the site (short of contacting the creators) but it has tons of games (taken from other sites) with a very easy to use interface. Like I said, it shows great potential but needs some tweaking.
