Today on Offworld we got the official announcement of Game Over/Continue? (above) -- Giant Robot and Attract Mode's previously mentioned upcoming art exhibit, and the first 'artxgame' collaboration that promises to bring together more indie developers and outside designers/illustrators than we'll see at the show. We also got a double hip-hop dose with The Ocarina of Rhyme, a free album that mashes the Zelda 64 soundtrack with Clipse, Dre, Aesop Rock and MF Doom, and the first full release of the DOOM/Ghostface collaboration put together for Rockstar's DS debut Grand Theft Auto: Chinatown Wars. Elsewhere we saw a NES emulator hack that brings drag and drop mouse control to Super Mario Bros, DIY customizable LittleBigPlanet Sackboy toys, urban toy progenitor Michael Lau's Metal Gear crossover toy revealed, more footage of retro-game mashup "compilation album" No Quarter, and the first pack of free bonus levels for iPhone fave Rolando. Finally, we saw Aquaria and World of Goo creators contributing to a cancer charity CD, played the fantastic new web game Transmover which mixes Lode Runner with Portal-like logic play, and highly recommended upstart gaming podcast A Life Well Wasted, a must-listen graduate of the This American Life school of production that sets the bar incredibly high for all others.
