And their most recent port, Knights in the Nightmare, is no exception. However, unlike Riviera: The Promised Land and Yggdra Union: We'll Never Fight Alone, which had minor control tweaks and a fresh update to their graphics, Knights in the Nightmare's original outing on the Nintendo DS utilized the unique touch-screen based features of the platform. And for those who played the original version or read our review of the game last year, they know this game has a unique gameplay style, to say the least. Does Knights in the Nightmare's PSP outing survive the transition to a more traditional control scheme, or is this a port that becomes a nightmare for those playing it?"
