White Knight has aspects that are "only possible on PS3"
In the latest issue of Famitsu magazine, Famitsu ran an interview with the developers over at Level-5. In addition to formally announcing the release date of the title as December 25, the interview revealed some other interesting tidbits. Expectantly so, the game has a huge budget, and is the biggest game the developer has dealt with thus far. Also, White Knight is possibly only one episode in a series of many, and a prequel is already on the drawing board.
Finally, and most interestingly, there is one aspect of White Knight that has yet to be detailed. This unknown feature goes far beyond anything seen in any RPG before it. It's also something that Level-5 claims can only be done on the PS3.
So what is this tightly-kept, secret aspect? It sure has piqued our attention! More on it as the game comes closer to release.
