At this week’s Electronic Entertainment Expo, the first new versions in five years of music-based videogames “Guitar Hero” and “Rock Band” were on display. “Guitar Hero Live” by Activision Blizzard offers the opportunity to play in front of crowds that react to the performance. “Rock Band 4,” by Harmonix and Mad Catz Interactive, focuses more on the guitar solos. “Both are attempting to revive a business that seemed dead in 2010 after the market was bombarded with more than 20 games between the two franchises, plus plenty more knock-offs, in a span of just five years,” suggests The Wall Street Journal. “The big question is whether the original music-game model is dead or finally ready for a comeback.”
