I've been seriously contemplating development of an iPhone game for the last few weeks. Now I have an idea and have been playing a few iPhone "MMOs" to get a look at the competition. Mostly, games like Kingdoms Live, and other identical "click" games, suck. The strategy is so dirt simple that it amounts to get income first, by sitting around and buying it, then start playing when everyone is essentially in the same boat. Not for me. A few days ago, I downloaded a game some of the players claimed was a better experience. It is, but it's still very different with what us "real" gamers are used to. It's called Kingdoms at War. I find it quite addictive. Like all of the games, it's meant to be played for a few minutes at a time, possibly as many as 15-20, many times throughout the day. It's a capital building game, where you explore land to build buildings to build troops that allow you to attack other players to get more money to explore more land... you get the picture.
