Guitar Hero Live introduces some really interesting ideas to the stagnant plastic-guitar genre, but the completely baffling refusal to offer piecemeal track/album/pack purchases and a reliance on a free-to-play model with, at best, rentals of songs brings it all to a screeching halt. Rock Band 4 might be more of the same, but it's the same functional, music-filled game we fell in love with. The gutted Guitar Hero Live, on the other hand, is considerably less of the same.
The entire package seems like a bold statement by Harmonix and Mad Catz. From the superior quality of the equipment to the shocking level of support for their past offerings, Rock Band 4 makes it very clear that the music genre can still shine as much as it did in its inception.
