My enjoyment of this game is mostly based on nostalgia. I don't know when or where I got this game, but I was VERY young when I played it. I remember I could never win a round, mostly because I had no idea how to even play the game.
Coming back to it many years later, its charm was not lost on me at all. The character designs were still memorable to me, and I even remembered the lyrics off a couple of the songs (especially Hiro's!).
That being said, a lot of the tracks were quite corny and aren't as memorable, but there are a couple of earworms.
The gameplay is interesting in that it actually relies more on rhythmical cues as opposed to visual (how about that for a rhythm game?). Depending on your sense of rhythm, after a couple of rounds this becomes second nature and the game becomes a sort of cakewalk. There are a couple of things that the game doesn't teach you such as how to use your Super or dodge the opponent's super (I personally couldn't find anything on this in the manual), but the general gameplay loop is quite simple.
I might revist Bust A Groove from time to time, but there are many other rhythm games higher up in my priority list.
