Using Your Smartphone to Conquer the World

A lot of us have dreamt of ruling the world; I've played out my megalomaniac fantasies in Civilization, one of my favorite desktop games.
It happens that there's a mobile version available. Like the PC version, Civilization 3 Mobile tests your empire-building skills. From the dawn of mankind up to 2100 AD, you become responsible for a people's destiny. Choosing the correct technologies to research, associating with the right allies, and maintaining a significant military force are crucial to your survival.
The good and the bad news: This game has gained at least one positive review for its faithfulness to the original version. But casual gamers might be turned off by the game's depth and complexity. At the very least, Com2uS has online documentation.
Don't Wanna Spend or Use a PDA/unsupported Smartphone? You might wanna check out Pocket Humanity, an open-source (and thus free) version created for pocket PC 2002-2003 and Windows Mobile 5.
