Tropico 3, you can achieve that end relatively quickly and cheaply. And with far less blood on your hands.
The Steam Special Edition version, which includes two additional maps for Sandbox mode and additional costumes and accessories for your avatar, will be available for 75% off over the next week -- a mere $7.50. And with the "Absolute Power" expansion now available for download, the offer becomes even more enticing. Viva El Presidente!
