Sometime between today and tomorrow, you’re going to need to pick up a PlayStation Store card. Maybe two. One of those 2gb or 4gb memory sticks might be a smart idea too. Atlus has just announced its own Black Friday-sort of sale.Technically and officially, it’s The Atlus Super-Mega-Ultra 50% Off PlayStation Network sale, but let’s just call it the Atlus PSP and PS3 sale for simplicity’s sake.

From November 16 until November 29, 2010, 10 PSP games and 1 PS3 game will be on sale for 50% off of the normal price…

When you think niche title, Knights in the Nightmare is the kind of game that comes to mind. There hasn’t been a game like it on the DS, or any other video game platform. In fact, it couldn’t work on any platform other than the DS. The required touch screen controls and somewhat complicated actions of the game could only be accomplished on the DS. This is a game that requires full attention, a DS with an immaculate touchscreen and the patience to navigate multiple tutorials.

Knights in the Nightmare is also a title that should look familiar to those who played Atlus’ Game Boy Advance and PSP games Riviera: The Promised Land and Yggdra Union. All three games are part of Sting’s Dept. Heaven series. While Knights in the Nightmare is the third game released, it is technically fourth in the series. Keep your eyes open for references to the earlier games…
