To be honest I bought this game because it is one that facilitates the installation of custom firmware on PSP's. It turns out it is also a pretty fun game. If you like tetris and things like that, you will surely like this one.

Sure you hacker kids may be not even playing the thing, just using it for you know what. But I actually found this game quite interesting! Just like tetris :) just with cool techno music and sweet themes. Computer vs player mode... all the good stuff. I've even played it vs another person on a 2nd psp. Fun stuff. I always win :) It takes a little to get into the groove but then once you have the strategy become 2nd nature you can really kick some ass. Sucks to play on challenge mode when it goes for over an hour. Feels like you've committed yourself to get as far ahead as possible, but you need to do things in real life too! It's like a drug, you just keep going. Till you get bored for the time being or just don't feel like playing for a long time, so you don't even wana start.

Really addicting and just seems to get better and better.

To everyone who gave this game anything under 4 stars needs to retire from the video game world. To all of you who complain that this game is to hard...go take a nap. This game is a little complicated at first but TRUST ME!! You will catch on very quickly and you will fall in love. (I made it to level 14 on my first try and currently get up to 78). This game is pretty hard when it comes to the vs. cpu mode but thats what makes it what is is. Graphics are great, sound is great, everything is great.

My favorite part of the game is when I work so hard to unlock a new skin (which can take very long by the way) and i finally get it it's like i just cured cancer.

Get this game now. ORDER NOW!!!!!!!

Shake ya body, shake ya body, shake ya body down to the ground......

THIS IS THE GAME YOU WANT AND NEED TO DOWNGRADE ANY PSP FROM A 3.5 TO 1.5. I FOUND IT AT MY LOCAL LIBRARY (for free) AND FOLLOWED ON LINE INSTRUCTIONS AND IT WORKED PERFECT. SO SAVE YOUR SELF THE 35 DOLLARS IF THATS ALL U WANT IT FOR AND TAKE A TRIP TO THE YOUR LOCAL BOOK EMPORIUM!

I'm finally able to downgrade my psp. Now I can write my own software to study on it!

This game is so much fun. It is probably one of the best games for the PSP right now. It is easy to learn, and surprisingly addictive. It is even more fun when you hook the PSP up to a speaker system.
