Family Computer Magazine covered the 1988 SCES with an almost 100% NES focus. There's not much that's unusual or unreleased to see here, except for Chesterfield by Vic Tokai, and the fact that Fist of the North Star was originally going to be named just "Ken."
This unreleased game was a Roguelike ("randomly"-generated dungeons with a limited view of unexplored rooms) with a weird cast of characters and enemies, and an automapping facility.
The graphics are a little spartan, but not so bad for this type of game. A shame it didn't come out.
