This may not be what you want....
This game has some new tracks that replace the music that was once found in all other versions of these games. Level one of Gokujō Parodius! has been changed as well as level one of Jikkyō Oshaberi Parodius. "That's the Way (I Like It)" has been shamefully replaced by Replaced by "Brilliant2U" from Dance Dance Revolution. "Mambo No. 5" the theme of the giant lips has been taken out and replaced by music that is annoying and very forgettable.

As well, the revival system it seems is only accessible in many titles if you choose the auto option at the start of your game. I'm not sure if only the BEST collection has this problem. Many reviews state the Asia and original Japanese version include all the original tracks.

Awesome game for on the go!
This is a great game for while sitting on the train on my way to/from work. The wacky characters and bosses brings a smile to me every morning. You don't need to know Japanese to figure out this game. Just shoot everything that moves. :)

Brilliant!
So much win contained in one small package! It's got 5 games in one, all good, though some are more fun than others.
Sexy Parodius deserves special mention!
