Go on a date with Ariane. Meet her at her home, have dinner, and choose from around 50 activities which can lead to success or failure of your night out.
Date Ariane is the original western style "date simulator" first published online in 2004. Three things that make it unique from Japanese dating sims is 1. it actually simulates a night out with a woman, 2. there is only one dateable character, 3. the graphics are 3D rendered images instead of anime style.
It has inspired over a hundred similar games since then. It was converted from an online game to a downloadable Renpy visual novel in 2015. Released as donationware it has had over 2 million downloads and translated in to 5 languages.
