LifePlay is a life simulation RPG that allows you to play in 92 (and counting) real world cities with real world buildings. The game has extensive character customizations and non-grindy gameplay and includes a range of life situations (434 scenes and counting) where your choice matters. The 3D sex scenes allow player control without forcing it, enhanced by well-written erotica.
Although this is only the 9th release, the game has actually been under development since the end of 2017, you can easily get a few hours of gameplay, especially if you try out different character builds in different maps. All game versions and their sources will be released to the public immediately. It's also very moddable, just check the Docs folder for information.
