Something like The Sims you mean? Also I think you should remake Animal Crossing made by Nintendo with many modifications and different things, that'd be awesome.
It'd be online of course.

Here's some top-selling ideas for an Animal Crossing remake:
1. Make animal and human interspecies sex an option
2. Make everyone a shota furry
3. Make an option to be like the motherfucking Jack the Ripper and kill a villager and bury her/his body after implied rape scene, maybe not exactly in that order, and get 100,000,000 bells and send the bones to the museum after time traveling 100 years into the future
4. Add guns and gore, yeah, everyone loves bloody furry shota guro figures with guns strapped on what was left of their bullet-inflicted heads
5. After brutally murdering almost everyone you know, furry Hitler rises and becomes chancellor of the village
6. You kill him to complete the game's main goal and get to live in a post-apocalyptic world off of furniture that would've been a huge rip-off to buy from anyone still alive
7. Your name is Joseph Stalin.
