Counterpoint: Do go play Universal Paperclips. It's a long term play. You'll lose a week or so immersed in it... but it's so good that then you'll lose any taste or desire for any of the other clicker games designed for longer time spans.
I'd say it took me ~3 days to complete in my first run (a few hours of play for 3 days).
I've got it down to about 3 hours. Not speedrun worthy, but yeah, proof that the game is short enough to complete in one sitting if you know what you're doing.
