GDC 2007 got up to full speed on Tuesday, and the 1Up Yours crew rode the crest of the wave. Sony gave the press a preview of its announcements including Home, Little Big World, and initiatives to help developers get the most out of PS3. 1up got plenty of first impressions of what could be the next step forward in online gaming. Garnett, John, Luke, and Shane also took in a day's worth of Microsoft games including an in-game demo of Mass Effect led by the Doctors themselves. You read right -- Microsoft pushing RPGs and Sony leading an online charge.
