[quote name='t65will']What were the main differences in gameplay between Amplitude and Frequency? I was really a big fan of Amplitude and at this price, I definitely want to give Frequency a try.[/quote]Been a while since I played them but off the top of my head... In frequency the tracks all ran along a sort of "tunnel," so like if you moved from track to track you'd be riding along the wall, along the ceiling, etc. Instead of having the tracks on a flat plane. And the multiplayer was split-screen. Plus there was a bunch of cosmetic differences, like you had a more generic indicator flying over the beats, rather than the spaceship you fly in Amplitude. Of course there were different songs, and Frequency had a "remix mode" (that may have been in Amplitude, I forget).
