as stated by a few others it depends on the genre, but further it depends on the gameplay, pacing, and numerous other design elements
Panzer Dragoon Saga is under 20 hours yet the length felt perfect
Shining force 3 is over 100 hours across all three parts and it felt perfect,
grandia 2 counter wise felt like it was dragging on forever at 25 hours
plus episodic design can alter good length, House of the dead overkill would be too long for a single sitting but designed to be taken in parts makes it's length perfect
