It’s definitely a Rock Band game. It’s a solid entry to the series and worth a playthrough, even in 2022, as it’s still somewhat supported by Harmonix releasing weekly DLCs and making sure the servers are working. The most difficult thing about this game is finding the instruments. It has all the fundamentals of a Rock Band game including tour mode, training, and being able to adjust the breakneck speed. The visuals and presentation are passable, doesn’t compare to Rock Band 2 or 3 with its venues and character customization but it’s still fine. The setlist is alright, it has some hits from well-known artists and then some alright picks from lesser known ones. Definitely the weakest setlist from the main series, however I didn’t really hate any specific track (even Dream Genie, it’s hard to play but fun to listen to). Birth in Reverse, Brown Eyed Girl, Friday I’m in Love, Short Skirt/Long Jacket, Still Into You, Somebody Told Me, and plenty of more fun on-disc tracks. So yeah, its a great little modernized Rock Band game that even though doesn’t have the same charm as its predecessors, it’s still pretty solid, especially considering how far these type of games have fallen since the 2010s.
