There are many amazing things that Band Fuse: Rock Legends does to revolutionize the way we play guitar, and it’s inspiring.
The multiplayer extensions are a blast (if you have that many guitars, or friends that can play), and the karaoke and backing track selections can really further the creativity. While the jumps in difficulty can be drastic at the higher levels, there's still plenty of ways to adapt, and BandFuse surprises at each step.
If your hope is that the Shred U teaching component will further strengthen your general technique or theory knowledge, you'll be significantly let down. You will make significant gains as a guitarist this way, but more because playing through the songs themselves is so fun.
BandFuse's biggest strength is the way it balances its gameplay elements with more serious guitar practice.
BandFuse: Rock Legends is a game with the technology to back up its great premise, but its flawed execution makes it a tough sell in light of its direct competition, Rocksmith 2014.
