https://www.identityrpg.com/ The idea behind Identity is it'll be an incredibly detailed version of essentially GTA5, but this only really scratches the surface. It looks similar to Second Life in a way with the amount of player-created content and customization and is essentially based off the Altis Life mod for Arma 3 as some of the original devs of this game are the creators of the Altis Life mod. This is a video explaining some of the detailed customization involved in just your apartment and hints at similar customization involved in creating gear like weapons and such. I'm even thinking the vehicles will be player crafted as well but haven't had any confirmation on it.
