I've started development on my next game, this one will be very different to my first release 'Cubix Challenge' (you can read about that here). What I'd like to find out is what is your favorite PHYSICS based game and why? Things of interest to me are... Are the physics super accurate or just fun? What is the performance like? What makes it so fun? Do you play it on iPhone or iPad? If you could add one thing to the game what would it be? Thanks so much in advance!
