Crave Entertainment to distribute ‘Tringo’: This guy wrote a computer game…inside of another computer game — the MMORPG Second Life. It’s the world’s first recursive video game.

Tringo, a cross between Tetris and bingo, was created by New Zealander Nathan Keir in Second Life, an online game where players have much freedom to create virtual objects with complex workings.

The game is now being distributed by Crave Entertainment as GBA Tringo for the Game Boy Advance portable game player, making the jump from the virtual world to the real one. […]

The game quickly became a craze in Second Life. Players bought copies of the game from Keir for around $50 each and set up Tringo halls and Tringo arenas, where players would go to compete for prizes in Linden dollars, the currency of Second Life.
