Pop'n Music 13 Carnival

This was the first game that I purchased from the PnM series and I must say it was nowhere near being a disappointment. Replayability level is high on this one; tons of fun songs and an easy unlocking system.

this game isent that worth it if you know atleast 2 or 3 songs this game is alright,sadly i only know 2 ,i am your Butterfly and Dragon Ball theme song.this game is a great addon but this is the first game i bought in the series,since ive seen many PnM videos around the net and i wanted to try it and so i bought this with the Pop n music controller 2
you should get this if you are tired of all the other songs

Personally I liked PnM 12 better, but there are several really cool new songs in this version that makes it worth buying. Lots of bonussongs to unlock and the unlocking is very easy. The game also has some new minigames that will keep you busy for 10 minutes or so :)
Overall, good as ever, but beginners might want to start off with a different version.
