Anyone who wants to, that's the hook, and it's why you can find so much weird stuff on there (like flying attack penises). You can create/edit objects in world and import textures/sounds/animations, and script everything together to make them do things. I wouldn't call it a game, though. You can certainly make a game inside of it (one particularly nifty one I saw was a beach where you could surf), but it's really just a 3D chat room most of the time.Second Life is such a weird game. I mean, it's graphics are worse than an old N64 game, but the ability to do anything is quite interesting. How exactly does one go about creating a gnome that can produce massive amounts of poo? Why is there poo in the game? Who put it there? Who does the programming on intercourse? Very strange.
