I promised some gameplay footage of Super Mario Galaxy's E3 2006 build, so here it is... I don't know if there are any differences compared to the final game -- if you do, please describe it in the comments? UPDATE: Some very thorough and thoughtful comments, thank you! - way more changes than I thought...! Let me know if you find this footage interesting...
