As someone who has been playing sports games since the NES, I can tell you first-hand that sports games have gotten ridiculously complex over the last 25 years. From two buttons in Blades of Steel to using every button, bumper, trigger and thumbstick on modern EA Sports NHL games, hockey games have changed a lot over the decades.
What appealed to me about Old Time Hockey is that it billed itself as an arcade hockey game. As someone who has been gaming for as long as I have, I was hoping that would mean hard-hitting, high scoring hockey with simple controls. That was correct to an extent but the execution hides the intention.
