Well, let's see... Again, if you don't like this genre due to the difficulty of managing the hand-eye coordination and timing accuracy of it all, you might not like
Frequency. However, all you have to keep track of is three buttons (Square, Triangle and Circle) to activate the music, and Left and Right on the D-pad to select a new track to attempt. (There's more to it for advanced users, but that's enough to get you started.) Also, in the 'Easy' difficulty setting, the timing accuracy is reasonably loose. If you hit the correct button pretty close to the correct time, you'll generally get credit for it. As you move up to 'Normal' and 'Expert' levels, however, the complexity of the tracks increases and the required timing accuracy reduces to a much more precise window. Why try for the higher difficulty ratings? There are two entire levels (five songs each) that are not available in 'Easy' mode. The 4th level requires you reach it in at least 'Normal' mode, and the 5th level is only accessible in 'Expert' mode. Oh, and the fifth song on each level is 'locked' until you achieve a certain combined score in the other four songs on that level...
So - what if you're not ready for 'Easy' mode? Well, there's a 'Tutorial' section that will help you out, as well as a 'Remix' mode. In Frequency's 'Remix' mode, you have the ability to remix songs 'freestyle'. You can make whatever sort of patterns you like, without worrying about matching an existant pattern. Want an easier than 'Easy' level to practice on? Make your own! Go into 'Remix' mode and make a really simple remix of the song and save it - then go into the 'Game' mode (on 'Easy' setting) and load your remix in the 'Custom' option at the song selection area. Now you can try to match your OWN remix! (P.S. - This also works equally well for people who want to try some really CHALLENGING mixes - or want to challenge others to try their mixes...)
