NHL Hockey on DOS is how I cut my teeth on 16 bit hockey, or should I say, 32 bit on PC. I played on keyboard and gravis gamepad, and it was glorious.
Sadly, the back in the day, my computer wasn't the fastest, so it wasn't as fluid as console version. It still holds significant real estate in my heart as nostalgia is concerned.
I am not entirely certain what engine it was built on, or if it was its own. It doesn't seem to play like the console versions. Gotta love that arrow icon for passing next to the player
I also loved the full seasons you could play.
