Ni No Kuni is a new JRPG due out later this month. You can choose to buy the game in retail stores, or you can download the game digitally via the PSN.
If you choose to download the game digitally, you may have look out for the space required for you to fit it into your hard drive. Ni No Kuni takes 19GB to download.
Please remember in order for the PS3 to download and install the game, you will need double the space. This means you will need to free up 38GB on your PS3 hard drive just to play this one game…
You can always get physical copy for the game if this sounds like too much hassle for you…
