What's your ideal game length?

Assuming the game is NES/Arcade in style and not a metroidvania, personally I'd like to see it at about the 1 hour mark for casual playthroughs, while speedrunning the game you could whittle it down to around 40 minutes after some practice.

I tend to prefer shorter games for the reason that it usually gives an incentive to the Devs to offer the player more game-altering options such as more unique heroes, pre-game modifiers/perks/custom game settings, extra modes (Boss Rush, Challenge Modes, Survival etc), multiple paths leading to different bosses, and difficulty settings that actually alter the gameplay in a meaningful way.
