There are games that have depth, such as GTA:CTW, Jet Car Stunts, Ravensword, space miner ore burst. Although I do admit there is a lack of deep games. Because of the price.
Hallejuhuih. The truth is true as always. The iPhone is a real platform with deep and challenging games. Along with casual awesome games.
i think it take some time to see more serious game titles. we do see better games and mature game developers this year already. we must know iphone can never compete with console games. their graphics and depth are far better.
