I’m not a gamer. However, a game has attracted me for its business potential: Second Life. It’s a game that has a 3D interface, with real people acting as participants in a virtual world very similar to ours, but you can do whatever you want there, as long as you do not disturb others: you can walk, meet and talk with others, own land, build properties, such as residences, offices/businesses, and so on. You can even fly. If you have a free weekend, don’t hesitate to try it, it’s very interesting and there are a lot of people already in the game: millions.
It’s just like a new country that you can live as second life in. But this second life is related to our life not only because you manage the character on the screen: the virtual money from that world can be exchanged with real dollars from the real world. This is possible because that world has an economy of its own and "real" money is nothing but a virtual thing in the real world, so this is perfect link. But don’t worry, you don’t need to spend anything in the real world except if you want to own land.
Just download and run it (its a 32 MB download, and when it installs it tooks less than 100 MB), and is 100% free. My character name is Sorin Donardson — see you inworld.🙂
