Hi-Fi RUSH is a hybrid of action and rhythm games. I think this is an excellent combination, as most action games are all about timing and rhythm already, so this is honestly a pretty obvious step to take. It’s also remarkably good at accessibility: It has multiple colorblindness filters and subtitle options, and the entire game environment moves with the beat, so you can time yourself visually even if you have a bad sense of rhythm. I enjoyed it a lot, even though the battles did get a bit too frenetic for me to follow at times. In particular, I think its best feature was sharply segregating combat and platforming sections; each combat encounter is a major one-time setpiece instead of you running into enemies all the time. jRPGs, take note.
I don’t want to talk about the gameplay, though. The story and writing are actually much more noteworthy. I believe it to be a very instructive example of Rebellion Chic: Despite being a cyberpunk story about a ragtag resistance fighting an evil corporation, its core messages are actually very conservative and pro-capitalist.
(Spoilers for the ending, but I don’t think they’re particularly ruinous.)
