Of all the game jams we enjoy writing about are the retro jams, whereby many developers from around the world come together to make a game in the theme of the jam. Previously for example it was the SpeccyJam 2 in which many fantastic games were developed in that ZX Spectrum style. Today though it's time for the finalized NESJAM and the rules did state that you must make a game using some of the basic limitations of the Nintendo Entertainment System. Thankfully many developers stood up to the challenge and gave us 23 fantastic games to play all in that NES graphical pallet!
