Before I go on, here are my 9.5 reasons: Afrika, Aquanaut's Holiday, Demon's Souls, Disgaea 3, Heavy Rain, LittleBigPlanet, LocoRoco Cocoreccho (this one accounts for that pesky .5), Katamari Forever, Siren: Blood Curse and Valkyria Chronicles.
The 10th reason, which popped onto my radar yesterday, is Ni no Kuni: The Another World.
Feast your eyes on the first (blurry) images of the PS3 version of Ni no Kuni.
For those of you who have never heard of Ni no Kuni, it's an RPG that's being produced by Level-5 (of Professor Layton fame) and Studio Ghibli, the Japanese animation studio responsible for Ponyo, Princess Mononoke and Spirited Away.
When the folks at Level-5 announced the DS version of Ni no Kuni all the way back in 2008, they also suggested--vaguely--that they were working on a console version of the game. Although most gamers assumed the console version would appear on the Wii, it was revealed yesterday (in the latest issue of Famitsu magazine) that it will appear on the PS3.
Unfortunately, little else is known about the PS3 version of Ni no Kuni at this point--other than it will allow gamers to "adventure in a world that has the feel of a Studio Ghibli anime."
