I’m not usually a big spender when it comes to iPhone games. Due possibly to past experiences on other phones, I’m often doubtful that any game playable on a cell phone would be worth $10. However, Electronic Arts’ release of “SimCity” on the iPhone was enough to make me take a chance. I’ve played “SimCity” games on the PC since the first installment back in the ’80s, and I half expected the iPhone version to be extremely trimmed down in terms of both features and appearance. However, the game surprised me with its depth and detail. It also left me feeling a little restrained.
