Why is it that so many 8bit and 16bit era video games had timers even when they served no specific purpose?
Design taken from arcade games. Gotta keep those coins coming.
Even if the time limits are too generous to ever be a threat on consoles they still serve a purpose. They are just badly designed for that purpose.
The only scenario I completely agree with your thought is when console games put a time limit on things like character and stage select screens.

Arcades used to have timers to provide an extra challenge. However most console games put the timer at such a generous amount that it really only matters on a few stages. It still does a good job of using psychology to discourage slow, tedious play.
