As a newly minted WoW-head (that's World of Warcraft for you noobs), I've always wondered just how all those "gold farmers" who try to sell virtual gold within in the game came by their vast, ill-gotten riches. I'd heard rumors of sweatshops in China where people are forced to drink Mountain Dew and kill Fel Orcs for 16 hours straight, but that sounded too strange to be true -- and, at the same time, not too different from the average college dormitory.

In a famous scene in the first Matrix movie, a character takes a bite out of a juicy steak. He knows it's not real, but enjoys it anyway. In some ways, a video game -- just moving pixels on the screen -- is a similar virtual reality experience. No, the aliens in Halo 3 are not real, but we pretend they are. That is how a game can pull you from a living-room couch into a foreign realm.

Tetris is one of the all-time classic video games, but its best suited to people with a lot of free time on their hands. Apparently, though, maneuvering those little polygons around a video screen still wasnt enough of a time suck for Swiss artist Guillaume Reymond. So, he set to work on a real-life version of the game with people in place of pixels.

Playing football videogames
is most fun when you’re pitted against your friends. For those of you who no longer live in a frat house, though, finding an opponent whenever you get the gaming jones just isn’t practical. But now there’s ESPN NFL 2K5 ($20 for Xbox and PlayStation2; espnvideogames.com). It creates computerized versions of your friends, saddled with their identical sorry style of play, so in their absence you can practice beating up on them.
