It was kind of weird foe me, too, but you get used to it. I even love the English version of the songs better now, except for the ending.

I think it's easier because you're used to the gameplay now. Most people say that the GBA game is so hard, but I got it after the DS one, and it didn't seem that hard at all.
And I'm pretty sure it's not just me, but the Japanese sounds are much more quiet. So for example at the shrimp level when the girl says one-two-three. But I think it's only in the European version.

Also, it's kinda funny that when you turn the sounds to Japanese, the subtitles at the Cheer Readers levels still follow the English version. :D

My last perfect was Remix 10. Which is kind of interesting, because the last remix wasn't my last perfect AT ALL in the previous games. Also, I really loved this installment.

Nice games. Are you interested in high score/fast time rankings?

Cyberscore has charts up with some pretty strong competition in all of your games.

And The Sonic Center features the most complete set of rankings for many Sonic games.

Moai Doo-Wop 2 was the second to last I did. Or was it Remix 9? I'm not sure, I did them the same day. My point is, you can actually memorize the stuff you have to do in Moai Doo-Wop 2, but you can't really memorize anything in Rhythm Rally 2. And you have to do stuff like the most times out of any games, and you only have to miss one not to get a perfect score.

Also, it took me AT LEAST half an hour before I got through Lockstep's practice at the first time :D But yeah, it's pretty easy now.

Yeah, some of them were much harder to get than others. For example, the last one I perfected was Rhythm Rally 2, and I perfected it like 2 weeks after everything else. I got better and better, and eventually I could do it. It was really satisfying

Yay, Rhythm Paradise! What an awesome game!
Are you planning to complete it? It may be a challenge, but it's worth it, if you ask me.
