I created a game called "Fantapong" that is pong with a class tree and stats for your paddle. I originally made this as a simple way to test HTML5/javascript. My co-workers love it. They think I should make it cross platform (ios, win32, android, osx, linux) and release it. I think the concept is simply a small advancement on pong and not worth it. I thought of ways to add value to the game such as cpu levels, missions like landing trick shots, and a quest system where you fight "monster" paddles.
Here it is (it requires 2 players):

Do you guys think copies of Pong are worth pursuing? Is the game design beaten to death at this point?
