What's your longest game play ever?

7 years, I believe. It's my only Perfection farm, and I usually move on to a new farm by year 4.

my first playthrough, without any instructions and promising myself to not go online and find the 'answers', 12 years 8 months 23 days...my only consolation is that my next playthrough only took 6 years 3 months and 11 days...oh, well
