You guys going commercial? I love it. Somehow the smell of capitalism makes my mouth water.
My opinion: For PONG add some new elements to the game once you have the basic handle down. I'm thinking bombs strewn about the arena, breakout mode, etc.
For Eclipse Galaga just make lots of cool powerups....sounds simple, but it makes a lot of space shooters successful.

Don't want to seem like I'm advertising, but when we seriously decided to buckle down on making an FPS we sat down and played all sorts of FPS games to see their strengths and weaknesses.
