I played the old EA NHL games like crazy, even the 1993 edition which was only licensed by the NHLPA for some reason, so this is so up my alley it's ridiculous: NHL 14 will include a mode where the game will play, look and sound like the original Sega Genesis/SNES versions of the game.
Of course the graphics won't be 16-bit pixelated, as you can see in the video above, but I like the emphasis on the old sound effects and the old control style as well as the classic star-shaped player indicator. Well done, EA!
