The reason I bought a Vita!
The game initially may seem a bit daunting because of all the terms and stats you need to keep track off, along with the voting system on the school board, but you can easily ignore most of that and just play it at your own pace.
You can either plow throught the amazing and funny story in 20-30 hours or spend 200 hours maxing your party and grinding the item world to buff up all your gear, it really has something for everyone (provided of course you like strategy rpgs or at least rpgs in general).
Have fun and dont let your dad step on your SlayStation portable and lose the 4million hours of gaming you put into it! :P
