So I downloaded this new game called 3D World cause its only $0.99 (plus sales tax). It a entertainment game and it's built using the Unity game engine. It looks very similar to paper pilot for those that have it. I think what is unique about this game is that it lets you explore an abandoned warehouse with great lighting effects and outstanding visuals. To me this is more of a tech demo of where the iphone unity engine will be taking games and hopefully FPS in 2009.
