I started to work with CryEngine Sandbox twelve years ago. (damn, already 12 years?) I also work with Game Maker and I'm learning with Unreal Engine 4.
Currently, I'm taking a pause from LKSD. To finish it, I need few longers whiles. I have only many short moments now, so I'm making a preparation for a new project I'm planning to start later. Looks like I've finally managed to effectively create a 3d terrain.
