Monte Cristo has released its fourth and final video in its "What is Cities XL?" series. This one asks whether you'll opt for open trade or self-sufficiency in your city and shows off the game's Avatar system, which allows you to create a character within your virtual world.

As we've reported, the Cities XL demo is now available to download until Oct. 6. It lets you create a city of up to 22,000 citizens on one of three map and contains approximately 10 percent of the full game. You can download the demo from eight different Web sites or look for it in the magazines PC Zone UK or PC Gamer UK.
