To be fair, this game plays pretty well, and the song selection is a good selection of 80's tracks for fans of that era. This should have been DLC though, as this does nothing to improve or push the series forward. If anything, this is a money grab from suckers like me who wanted more songs to play with their plastic instruments. Unless you really, and I mean really, like the setlist, don't even bother getting this one.
If Guitar Hero 2 had released in the day & age of DLC, the songs in this game would've likely just been ones you could add to it. Rocks the 80s is essentially GH2.5 ---- and I am a-okay with that. Same tried-and-true gameplay with a new, albeit slightly shorter, setlist of songs to shred to. Introduced me to some new bands & helped me continue to foster my growing love for classic rock.
