None of them had a fraction of the push Soul Sacrifice is receiving.
Soul Sacrifice has a lot of hype, lot of advertisement, lot of marketing, it's in one of the most popular genre nowadays, it's coupled with the price cut of the console. I thought it had much bigger expectations than selling "just" 150-200k. Then of course, Vita is selling bad and userbase is tiny, but still: if Sony is giving this push it's because it wants Soul Sacrifice to sell well, and to push hardware, otherwise they would have launched it as Gravity Daze last year, without creating any buzz around the game.
