There is one game released this month that stands among the rest, and to this day is a great challenge, and actually still a fun game. It is Ghosts 'N Goblins for the NES. sure, it's insanely difficult, but gamers had already experienced the Mario challenge and were looking for somehting more challenging. This certainly fixed that demand. Commando and 1942 were also released this particular month, and to me, were pretty much the same game, another Space Invaders essentially, but I found 1942 more fluid and more plausibly beatable. However, Ghosts N' Goblins was this month's breakout game.
